Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. Through electrolysis, a metal film is attached to the surface of metal or other materials, which prevents oxidation of the metal, improves abrasion resistance, electrical conductivity, reflectivity, corrosion resistance, and enhances aesthetics.

Basic Concept of Electroplating
Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. Through electrolysis, a metal film is attached to the surface of metal or other materials, which prevents oxidation of the metal, improves abrasion resistance, electrical conductivity, reflectivity, corrosion resistance, and enhances aesthetics.
Application areas of electroplating treatment
Plating technology is widely used in modern industry, especially in the electronics industry, communications and military and other fields, a large number of functional plating technology. In addition, anodizing is often used to change the appearance of products and improve the surface color and texture structure, and is commonly used in the surface treatment of titanium and aluminum.
Plating Process
The plating process consists of several major steps:
Pre-treatment: Ensuring that the surface of the workpiece is clean and free of oils and impurities is critical to the success of electroplating.
Electroplating: In an electrolyzer, metal ions are reduced to metal atoms under the action of a DC electric field and deposited on the surface of the workpiece.
Post-treatment: Including passivation treatment, hydrogen removal treatment, coloring treatment, coating treatment and sealing treatment, etc. to improve the corrosion resistance, gloss and stability of the plated layer.
Importance of plating treatment
Plating is not only a means of protection and decoration, its functional use is becoming more and more extensive. Reasonable post-plating treatment process is crucial to ensure the performance and service life of plated parts.
