Electroplating process: Electroplating refers to the use of the base metal to be plated as the cathode in the salt solution containing the metal to be plated. Surface processing method. The properties of the coating are different from those of the base metal and have new characteristics. According to the function of the coating, it is divided into protective coating, decorative coating and other functional coating.
Electroplating process: generally includes three stages of pre-plating pretreatment, electroplating and post-plating treatment.
Requirements for the electroplating layer:
1. There should be good bonding force between the coating and the base metal, the coating and the coating.
2. The coating should be finely crystallized, flat, and uniform in thickness.
3. The coating should have a specified thickness and as few pores as possible.
4. The coating should have the specified indicators, such as brightness, hardness, conductivity, etc.
