Nickel plating film is generated by electroplating nickel through electrolysis or chemical methods

The method of electroplating nickel or a nickel layer through electrolysis or chemical methods is called nickel plating

Nickel has good chemical stability in atmosphere and alkaline solution, and its color is not easily changed. Although it only oxidizes at temperatures above 600 ° C, it slowly dissolves in sulfuric acid and hydrochloric acid and easily dissolves in dilute nitric acid. Good corrosion resistance, easy to passivate in concentrated nitric acid.

Nickel coatingHas high hardness, simple polishing, high reflection of light, and other aesthetic qualities. The disadvantage is porosity. To overcome this drawback, multiple layers of metal coatings can be used, with nickel as the intermediate layer.

Application:

Usually used to prevent corrosion and enhance aesthetics. Therefore, decorative coatings (energy-saving lamp caps, coins, hardware, etc.) are usually protected. Nickel plating on copper products is an ideal choice for corrosion prevention, but due to the relatively high cost of nickel, copper tin alloys are often used instead of nickel plating.
Metal nickel platingWhat are the benefits of it?

As a base layer, it connects the substrate and the working layer, increasing the bonding strength;

2. Improve the flatness of the coating, increase brightness, and have good decorative properties;

3. The coating has good density and rust resistance;

4. Size repair, some mechanical parts may be increased in size by electroplating nickel.

5. Wear resistance, usually co deposited with some functional powders, such as polytetrafluoroethylene powder, aluminum oxide, silicon carbide, diamond, etc., to form a functional composite layer.
