Surface treatment is a process of artificially forming a surface layer on the surface of the substrate material that is different from the mechanical, physical and chemical properties of the substrate. The purpose of surface treatment is to meet the requirements of corrosion resistance, wear resistance, decoration or other special functions of the product.
plating
Electroplating (galvanizing, nickel, copper, chromium, zinc-nickel alloy, etc.): is the process of plating a thin layer of other metals or alloys on the surface of some metals using the principle of electrolysis, which is the use of electrolysis to make metal or other material parts The process of attaching a metal film on the surface of the metal prevents corrosion, improves wear resistance, electrical conductivity, light reflectivity, and enhances aesthetics.
The main purpose of electroplating
1) Improve the corrosion resistance of metal products or parts. For example, the surface of steel products or parts is galvanized.
2) Improve the protection-decoration performance of metal products. For example, the surface of steel products is copper-plated, nickel-plated and chrome-plated.
3) repair metal parts size. For example, important mechanical parts such as shafts and gears are worn out after use, and their sizes can be repaired by iron plating, chrome plating, etc.
4) electroplating can also give a certain product or part a special function. For example, hard chromium plating can improve its wear resistance.
