Electrolysis nickel Plating is the process of plating a layer of nickel on the surface of ferrous or nonferrous metal parts by electrolysis. It can be used as a surface coating, but mainly for chrome primer, to prevent corrosion and increase wear resistance, gloss and appearance. It is widely used in machinery, instruments, meters, medical equipment, home appliances and other manufacturing industries.
Electroless nickel plating layer is highly stable in the air. Due to the strong passivation ability of metallic nickel, an extremely thin passivation film can be quickly formed on the surface to resist the corrosion of the atmosphere, alkali and some acids.
Electroless nickel crystals are extremely small and have excellent polishing properties. The polished nickel coating provides a mirror-like glossy appearance while maintaining long-term gloss in the atmosphere. Therefore, the plating is often used for decoration.
The hardness of Nickel coating is relatively high. Nickel Plating can improve the wear resistance of the surface of the products. In the printing industry, it is used to increase the hardness of the lead surface.
Due to the high chemical stability of metallic nickel, some chemical plants also commonly use thicker nickel coatings to prevent corrosion by the media. Nickel plating is also widely used in functional areas, such as the repair of worn, corroded parts and the use of brush plating for partial plating.
Nickel plating is widely used as a protective coating on steel, zinc die-cast, aluminum and copper alloy surfaces to protect the base material from corrosion or as a shiny decoration coating.
