Steel ball plating process

Electroplating is an electrochemical process occurring at the interface between metal and electrolyte. Obviously, in order to ensure the quality of electroplating products, in the field production must strictly ensure that the electrolyte and the plating surface always maintain good contact, if the contact between them is bad, the electrochemical reaction can not be carried out. Due to improper pretreatment process or maintenance operation, the oil, rust and oxide skin attached to the surface of the metal plating parts hinder the direct contact between the electrolyte and the plating parts. They are sandwiched between the coating, will cause the quality of the product is not good, so the metal plating surface cleanliness and surface status is the first condition to obtain high quality coating. For a long time, most of the quality accidents in production are not due to the plating process itself, but mostly due to improper treatment before plating. Therefore, the coating smoothness, adhesion, corrosion resistance and other properties are closely related to the pre-plating treatment.
