1. Mechanical Surface Treatment: Sandblasting, Shot Peening, Polishing, Painting, Oiling……

2. Chemical Surface Treatment: Blue, black, phosphating, acid pickling, chemical plating of metals and alloys, TD treatment, QPQ chemical oxidation treatment...

3. Electrochemical Surface Treatment: Anodizing, Electrochemical Polishing, Electroplating...

4. Current Surface Treatment: Chemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), Laser Surface Treatment, etc.

The aforementioned aspects are not types, such as dry shot blasting, wet shot blasting, abrasive water jet, and air-water shot blasting processes...Painting includes electrostatic painting, flame spraying, powder coating, plastic spraying, plasma spraying, and explosive spraying processes...Electroplating includes copper plating, chrome plating, zinc plating, and nickel plating...For instance, electroplating processes can be divided into acidic and alkaline copper plating based on the different pH values of copper plating. According to the main components of copper ions and electrolytes, there are cyanide copper plating, pyrophosphate copper plating, citrate copper plating, sulfate copper plating, tartaric acid copper plating, borofluoride copper plating, and bright copper plating.
