What are the common surface treatment processes for materials used in medical device manufacturing?

Common surface post-treatment processes used in the medical industry include:

Oxidation treatment: Oxidation treatment is a surface treatment process that can form an oxide film on the surface of a metal, thereby improving its corrosion resistance and biocompatibility.

Sandblasting treatment: Sandblasting treatment is a surface treatment process that can use high-pressure nozzles to spray small particles onto the surface of a material, thereby improving surface smoothness and quality.

Plating treatment: Plating treatment is a surface treatment process that can plate a layer of metal on the surface of a metal. This treatment can improve the corrosion resistance, wear resistance, and appearance quality of the metal.

Coating treatment: Coating treatment is a surface treatment process that can spray a protective coating on the surface of a material. This treatment can improve the corrosion resistance and appearance quality of the material.
