Why are most metals plated with chromium?

Chromium, a bright white metal with a slight bluish tint, is electrochemically or chemically coated with a layer of chromium on a metal or some non-metal, known as chrome plating. Chromium metal is easily passivated in the air, forming an extremely thin passivated film on the surface, thus showing the properties of precious metals.


One of the main options for metal plating is chromium plating. Chrome plating has some unique advantages that make it the best choice for metal plating in many situations.


Chromium basic introduction


1. Lack of corrosion

Corrosion is an important problem with metal items because it can damage the structural integrity of metals and destroy them over time. Fortunately, chrome plating prevents corrosion.


Chrome plating is popular in applications such as body parts prone to rust because it prevents rust. The auto industry consumes more chromium than any other industry.


2. The ability to withstand extreme weather

Chrome plating gives the material strength by making it resistant to extreme weather damage. Chrome plated articles are not easily damaged by extremely high or low temperatures. They are also not damaged by high or low humidity.


Chrome's ability to withstand extreme climates makes chrome plating ideal for reinforcing items that need to be used outdoors in extremely harsh climates.


3. Restore to the new state

The chrome layer covers the product with a coat of paint, giving it a completely new look. After chrome plating, items look brand new and will lose any previous physical glitches.


Chrome plating is a cost-effective way to restore an old item to a new condition.


4. Nice look

Chrome plating is often chosen for its smooth, sleek appearance as a way to beautify products and parts. Chrome plating is a relatively simple process that can give items a whole new look, feel and surface features.


The chrome finish is shiny. The aesthetic appeal of chrome plating makes chrome plating a popular choice for items that will be highlighted and decorated.


5. Lack of substrate metal effect

Another advantage of chrome plating is that it does not damage the substrate. Because this type of coating can be plated even at lower temperatures, the substrate is not damaged during chrome plating.


When metal plating is performed at higher temperatures, it usually results in some deterioration and weakening of the substrate.


6. Processing of complex forms

Metal coatings are sometimes limited in coating objects of abnormal and irregular shapes. However, chrome plating can be used on irregularly shaped items or even on objects that contain holes or holes in their design. Therefore, chromium plating is a widely used metal coating.


7. The power of persistence

Some types of metal coatings do not adhere to the substrate as reliably as chrome coatings. The adhesion strength of the chrome-plated layer improves the durability of the articles used.


The chrome layer is so strongly attached that flaking and/or delamination is highly unlikely. The strong adhesion of the chrome layer maximizes the service life of the chrome layer and minimizes the need for repair or maintenance over time.


8. Lubricity

Chrome plating is probably the best lubricity of any other metal plating method. The lubricity of chrome plating is advantageous in many ways. These lubrication advantages contribute to the engineering value of chrome plating.


Lubricity minimizes friction between moving parts. Lubricity also gives chrome plated products higher wear resistance and wear over time.


In addition, the lubricity of chromium plating minimizes the chance of chafing. Abrasions describe wear and tear on the surface of a metal caused by adhesion forces caused by sliding between materials, moving sideways.
