Surface treatment is a process method that artificially forms a layer on the surface of a base material, possessing mechanical, physical, and chemical properties different from those of the substrate. The purpose of surface treatment is to meet product requirements for corrosion resistance, wear resistance, decoration, or other specific functional characteristics.
Electroplating
Electroplating (zinc plating, nickel plating, copper plating, chromium plating, zinc-nickel alloy plating, etc.): This is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. It utilizes electrolytic action to make a metal film adhere to the surface of components made of metal or other materials, thereby serving purposes such as preventing corrosion, improving wear resistance, conductivity, reflectivity, and enhancing appearance.
Main Applications of Electroplating
1. Improve the corrosion resistance of metal products or parts. For example, zinc plating on the surface of steel products or parts.
2. Improve the protective-decorative properties of metal products. For example, copper plating, nickel plating, chromium plating, etc., on the surface of steel products.
3. Repair the dimensions of metal parts. For example, important mechanical parts like shafts and gears that have worn out after use can have their dimensions restored by processes like iron plating or chromium plating.
4. Electroplating can also impart specific special functions to certain products or parts. For example, hard chromium plating can improve wear resistance.
