WebAug 11, 2024 · Passivation is an acid-cleaning process designed to remove free iron from the surface of stainless steels. This process is an essential step in removing foreign matter from the surface of the metal and creating a chromium-rich layer that is resistant to corrosion. The process effectively prolongs the part’s lifespan. WebChromate conversion coating or alodine coating is a type of conversion coating used to passivate steel, aluminium, zinc, cadmium, copper, silver, titanium, magnesium, and tin alloys.
