Chrome, Nickel, Bluing? Chrome and nickel difference. Defect of coating shiny nickel-chrome What is the difference between nickel plating and chrome plating

Chrome vs Nickel

When deciding what you will choose for your home and business, it is always important to be confident in the result you want to achieve. This is because, like clothing and footwear, trimmings are also going out of style. V recent times finishes such as chrome and nickel are very popular with households and even businesses. These are two types of finishes that can be easily adapted to modern technology and equipment, whether in the kitchen, in the bathrooms or in the rooms. They deliver an elegant and clean finish. Chrome and nickel have a silver tint. Therefore, before choosing what you want to use for your finish, it is always wise to look at how they differ from each other in the first place.

The chrome finish is very shiny, reflective and has a mirrored finish. Some people also prefer this because it looks timeless and classy. It is popular not only in household lighting, but also for other uses such as fishing lures and the automotive industry. Not only is it attractive due to its silver hue, but it is also very durable. It does not corrode and can withstand intense temperature and weather. There is no such thing as hard chrome, but they are actually materials like metal, copper or steel that are chrome plated. There is a bit of a lack of chrome trim. Thanks to their smooth, mirrored surface, they easily show signs with the naked eye, such as fingerprints, water stains and even scratches. Despite this, chrome does not tarnish over time, unlike nickel, which has a slightly cloudy tarnishing.

Unlike the cooler chrome finish, the nickel finish has a warm and silver tint. From the 1900s to the 1930s, this was the standard fit in kitchens and bathrooms. It's not shiny like chrome, but it has a rather dull or matte finish. Nickel also gives an antique look. The upside when choosing a nickel plating is that due to its matte or dull finish, the absence of marks and scratches will not be an issue. It doesn't show fingerprints or watermarks like shiny ones. In addition, nickel does not wear out easily, but it will tarnish over time. Despite this, it is very durable and can withstand extreme temperatures and humidity. Nickel is also cheaper than chromium.

Both chrome and nickel have their own advantages and disadvantages. Good way deciding what to use in between is to start and see what you want to finish is already in the house. You should also keep in mind that chrome is slightly more expensive than nickel, but a little more cost won't hurt if you want to achieve that shiny finish. You should also consider if you are too prone to detail, because shiny surfaces such as chrome can slightly maintain maintenance due to the appearance of imperfections compared to dull nickel plating. Nickel finishes also tend to tarnish over time. However, they are both durable and don't wear out easily.

1. Chrome has a mirror finish and nickel has a matte matte finish. 2. Both are durable and can withstand extreme temperatures. 3. Nickel can tarnish over time, but chrome does not. 4. Due to the shiny chrome finish, it can easily show imperfections such as fingerprints and scratches. Nickel, however, does not show these marks. 5. Chrome is slightly more expensive compared to nickel. 6. Due to the visibility of fingerprints or watermarks on chrome, slightly more maintenance is required.

Chrome and Nickel

In their pure form, these "cousins" are found only as coatings, and the first nickel-plated items date back to the 19th century. Chromium began to be used later. However, the bulk of their production is spent by industry not at all for coatings, but for the production of alloy steel - stainless, heat-resistant, chemically passive, etc.

Nickel acquired its melodious name a long time ago: in medieval Europe, sometimes they came across an ore very similar to iron, with an unpleasant exception - it was not possible to smelt metal from it under any circumstances.

Of course, the fiasco was attributed to the machinations of malicious dwarfs-kobolds (hence the cobalt) and devils (in Western Europe, one of the common names for the devil is Nick). Then, when it turned out that the ore did not contain iron at all, but a completely different metal, it was named in memory of past delusions.

Nickel plating is most popular among household utensils - from kerosene lamps and samovars to beds and bicycles (the automotive world was connected later) - due to its durability and nobility. It is quite resistant to water in all its manifestations, but only on condition that the film is applied accurately and correctly, otherwise we will see a widespread picture of surface ulceration by multiple caverns and shells of the most different forms and sizes - from microscopic to the size of a grain of rice. This happens when the item is kept damp for a long time. The ubiquitous moisture, penetrating to the gland through pores invisible to the eye, forms local foci of corrosion. If the damage is not catastrophic, it is enough to carefully grind the product with fine finishing sandpaper (the so-called "micron" or "zero") and somehow preserve the result. From time to time, you can rub the surface with machine oil or cover it with a thin layer of durable colorless varnish (best of all, zapon) - it all depends on the specific situation. Unprotected metal stored in indoor conditions, of course, it will no longer be covered with a rash, but the exposed iron will darken, which will not happen with oil or under varnish.

A less drastic way is to soak the item in kerosene. The latter, possessing a strong alkaline reaction and amazing penetrating ability, will gently dissolve rust at its place of residence.

When the nickel film has peeled off with a continuous flap, which is not so rare due to poor-quality preparation of the base, it remains to carry the product to the nearest factory or auto repair shop where there is a working galvanic section.

A good nickel plating, while maintaining its original integrity, fades over time, twitching with a bluish haze. In this case, it is simply polished, although the former shine usually cannot be returned. Old guidelines recommend removing blue stains and dull plaque with a solution of sulfuric acid in alcohol (1: 1), but this is too much. You can see an example of the restoration of a nickel-plated object (a kerosene lamp) on one of the colored inserts.

Chromium is much harder than nickel, and its films are stronger, do not tarnish, but pitting corrosion finds food here too. The methods of dealing with it are similar.

Good afternoon, Oleg light Antoshkiv!

I actually just came out like that Monday March 28 2005 00:01,
here I hear - Oleg Antoshkiv says All (well, I butted, of course):

OA> The question is purely out of curiosity: what is the difference between chrome plating and
OA> nickel plating?

I hope this is a rhetorical question. Or explain.

OA> I know that both are used to cover metal
OA> surfaces to make them shiny and to protect them from corrosion.
OA> How to distinguish a chrome-plated surface from a nickel-plated one by eye?

Nickel is slightly yellowish, chrome is slightly bluer.

OA> What is the difference in mechanical strength, chemical resistance?

For improvised and home chemistry, both are absolutely resistant.

OA> The difference in cost?

Chrome plating is necessarily more expensive.

OA> Is the coating technology the same?

Very different. For example, traditional bumper chrome technology
it is nickel - copper - nickel - shiny. nickel - chromium on steel. or without the first
nickel sublayer, if you obtain a permit for copper from cyanide el-that.

If it seemed to you that there are just one-layer
decorative and anti-corrosion coatings, then only the Sino-underground clock.
Half a micron of chrome or gold on bronze is enough for a couple of weeks of wearing.

OA> Is there a difference which metals can be coated with both?

The difference is in technology, but in general, any can be covered with anything.

Why do you need to find out what is where, or did you go yourself? The last "M-nee, not
I advise, they will eat it! "(C)

For sim forever and so on. Leizer (ICQ 62084744)

OA> nickel plated?

The nickel is usually just white, and the chrome finish can change color, although
usually slightly purple.

OA> What is the difference in mechanical strength, chemical resistance?

Chrome plating gives a harder coating than nickel, chemically chromium
continues to protect the base metal (if it is steel) with minor damage
coating, in the case of nickel corrosion is only accelerated when the coating is damaged.

OA> The difference in cost?

fig knows him

OA> Is the coating technology the same?

At least on steel products, chromium is deposited directly, and nickel
through the substrate (copper).

OA> Is there a difference which metals can be coated with both?

The color is different.

Chromium is better in these parameters.

OA> The difference in cost?

Before nickel plating, the metal is plated with copper and polished.
Before plating with chrome - the metal is plated first with copper, then with nickel and
only then with chrome. Then the coating is durable.

OA> Is the coating technology the same?

Different, it's better to forget about chrome at home. Chromic anhydride is used,
which is very toxic.

OA> Is there a difference which metals can be coated with both?

It all depends, if I'm not mistaken, on the activity of the metal.

Chrome, Nickel, Bluing? Chrome and Nickel difference

Nickel - Chemist's Handbook 21

from "Theory of Corrosion and Corrosion-Resistant Structural Alloys"

Pure nickel is now used to a limited extent as a structural material. It has been almost completely replaced from the chemical industry by corrosion-resistant steels. Nickel is occasionally used in some industrial and laboratory facilities mainly due to its extremely high resistance to alkalis. Nickel is widespread for protective and decorative (mainly electroplated) coatings on iron and steel, as well as copper alloys (in order to increase their resistance to atmospheric conditions). There is also information about the use of nickel-clad iron in the chemical industry. Nickel is slightly more electronegative than copper (see Table 2), but it is noticeably more positive than iron, chromium, zinc, or aluminum. The equilibrium potential of nickel is -0.25 V, the stationary potential is 0.5 N. Na l-0.02 V. Unlike copper, nickel has a noticeable tendency to go into a passive state (see Chapter II). These circumstances largely determine the corrosion characteristics of nickel. In oxidizing environments, nickel alloys with chromium additives are easier to passivate and acquire corrosion resistance in more acidic oxidizing environments compared to pure nickel. It is also worth emphasizing the excellent resistance of nickel to alkalis of all concentrations and temperatures. Nickel, along with silver, is considered one of the best materials for melting alkalis. Nickel can also impart this property to a large extent to high-nickel steels and cast irons. Nickel is very stable in solutions of many salts, in sea water and other natural waters and in a number of organic media. Therefore, it still finds some application in the food industry. Nickel is quite stable under atmospheric conditions, although it tarnishes somewhat. However, if there is a significant amount of SO2 in the atmosphere, then there is a more noticeable atmospheric corrosion of nickel. The most widespread of the copper-nickel alloys, in addition to the cupronickel-type alloy, is an alloy based on nickel with copper of the Monel type, containing about 30% Cu and 3-4% Fe + Mn, and sometimes also a little A1 and Si. This alloy, in comparison with pure copper and nickel, has increased resistance in non-oxidizing acids (phosphoric, sulfuric and hydrochloric and even medium concentrations of HF), as well as in solutions of salts and many organic acids. The corrosion resistance of monel, as well as copper and nickel, decreases markedly with increasing aeration of the medium or the access of oxidants. These alloys are characterized by increased anti-corrosion, high mechanical and technological properties and relatively high strength. They roll, cast, press and cut well. In the rolled state, OV is 600-700 MPa and 6 = 40-45%. These alloys are good structural materials for some chemical devices operating in low concentrations of h3SO4 and HC1, as well as in acetic and phosphoric acids. It should also be noted that the Monel-K alloy, which is close in corrosion characteristics, has a composition,% 66 Ni 29 u 0.9 Fe 2.7 Al 0.4 Mn 0.5 Si 0.15. This alloy is characterized by aging hardening. In this state, it has high (for non-ferrous metals) mechanical properties ab = 10OO MPa at 6 = 20%. Monel-K is used for the manufacture of parts of machines with significant power loading, for example, parts of centrifugal pumps, as well as for bolts, if it is impossible to use steel due to its insufficient durability or the danger of hydrogen formation. The scarcity of the initial components - nickel and copper - severely limits the distribution of alloys based on them. Alloying nickel with molybdenum (over 15%) gives the alloy a very high resistance to non-oxidizing acids (see Fig. 86). The broadest practical use find alloys of a similar type, the composition of which (% by weight) is given below. In addition, Hastelloy C sometimes contains 3-5% W. All these three alloys are also quite stable in most organic media, alkalis, sea and fresh water. Along with high chemical resistance, they have great strength, are a valuable material for chemical engineering and aiparato. They can be obtained in the form of strips, plates, pipes, wire, they are able to be welded, cast. Their use is limited by their high cost and some technological difficulties (forging, rolling). Nickel-chromium alloys (nichrome) are heat-resistant and highly heat-resistant and acid-resistant materials. NiCr alloys containing no more than 35% Cr are solid solutions based on the γ-lattice of nickel (austenite). Since chromium and chromium-rich a-phase with the usual content of interstitial impurities (C, N, O) are very fragile, the content of 35% Cr should be considered the limiting one for obtaining ductile alloys. However, alloys containing more than 30% Cr, in practice, are still too hard, and their processing, even at elevated temperatures, is difficult. It has been established that the purer the alloy is in terms of other impurities, mainly interstitial impurities (C, N, O), the higher the chromium content is permissible without fear of impairing the possibilities of technological processing of the alloy. If it is necessary to obtain very plastic nichrome (for example, for drawing a wire of 0.01-0.3 mm), the chromium content in silave usually does not exceed 20%. Alloys containing 25-30% (sometimes up to 33%) Cr are used for the manufacture of thick wire and strips. They are distinguished by maximum heat resistance, along with high heat resistance and an extremely slow grain growth rate at elevated operating temperatures. Therefore, nichrome, unlike heat-resistant alloys of the Fe-Cr-A1 system (limped), do not so noticeably lose their plasticity after operation at high temperatures Oh. In order to partially replace nickel, improve machinability and technological properties at high temperatures, sometimes up to 25-30% Fe and more (ferroiichromes) are introduced into these alloys. phosphorus and even carbon are considered harmful impurities that reduce the ductility of the alloy. The presence of no more than 0.02-0.03% 5, 0.05% P in the best varieties vacuum melting nichrome up to 0.04-0.07 and in ordinary technical nichrome up to 0.2-0.3% C. Manganese is used as a deoxidizer, in addition, it contributes to grain refinement during primary crystallization and can be allowed in alloys such as nichrome up to 2% (sometimes higher). The aluminum content is usually allowed no higher than 0.2% (in special alloys up to 1.2%), silicon is not higher than 1%, molybdenum is sometimes specially introduced into nichrome (in an amount of 1-3, and sometimes up to 6-7%) to increase the corrosion resistance to chlorine ions, as well as heat resistance.

Chrome, Nickel, Bluing?

People's Commissar 02-05-2011 13:01

If the topic is not in that section, then please move it to the desired one, because I did not find a suitable one.

Gentlemen forum users, tell me who knows. I'm going to take Flaubert's 4mm Cuno Melcher Magnum revolver. There is a choice: Chrome, Nickel, Voroneny. Since the search on the Internet did not give any results, I decided to turn to knowledgeable people: which is better to take ??? What are the pros and cons, what is more durable and corrosion-resistant ???

PS: The difference in price is not scary, only the quality is of interest.

Groz 05/02/2011 15:16

This is not for wearing, my IMHO is blued. The front cut of the drum will not be so hemorrhagic to clean. But for wearing it is better to use stainless steel.

Idalgo 02-05-2011 17:26

I am for stainless.

Foxbat 03-05-2011 12:53

Nickel is cute, but it's still a coating, and soft. In addition, it does not protect against corrosion by itself, it is porous. If done not quite right, it will rust, which is very noticeable on the mass of cheap edged weapons of the late 19th - early 20th centuries, when they were fond of. Black spots of corrosion appear on it, especially if it is damaged.

Here, no matter how you throw it, you can't think of a better stainless steel!

By the way, chrome is a very rare coating for weapons, I have never seen it on the mass market (I’m not saying that it doesn’t happen, I just didn’t see it), only on an expensive sports one.

If you choose from nickel-plated and "blued" for silumin, then definitely take nickel. "Bluening" it peels off once or twice. But chrome - it would be much more serious. My 1911 frame (steel) has a matte Hard-Chrome finish - it looks good, doesn't scratch and hardly gets dirty.

The chromium coating is porous by nature, and the porosity strongly depends on the modes (the faster the coating is, the worse if the sclerosis does not fail). Porosity is unimportant, for example, in hydraulic equipment (all the same, everything is in oil), but it is critical in weapons, where any aggressive filth accumulates in micro-matter. Moreover, it rusts under the chrome, at first it is not visible, and when it comes out, it is too late to drink Borzh. Therefore, expensive weapons (barrels in any case) are usually not chrome plated, but are either made entirely of stainless steel or from traditional materials. And nickel plating must be distinguished between electrochemical (electroplating, like chromium) and chemical - smoother (there is no increase in the current density on microroughnesses and the growth of coating material on them), possibly not porous (I will not argue), can be done at home.

If the alloy is aluminum, then the black coating is most likely obtained by anodizing. There it is possible, depending on the composition of the electrolyte, to obtain the desired color, moreover, the oxide film obtained during anodizing is easily colored even with aniline dyes. Over time, it may fade in places. Oxidized aluminum is usually gray-green in color. Nickel plated chemically very durable, but thinner than electrolytic. But to cover something with black chrome is fucking how to have sex - too capricious process. Among other things, the coating on aluminum alloys can be applied by gas-plasma spraying, and here the composition of the coating is limited only by the imagination of the "dustmen"
