Passivation

Commonly used chemical surface treatments are mostly used on steel and stainless steel, where a thin layer of protective material is used to create the housing to enhance corrosion resistance or reduce chemical reactivity. Stainless steel passivation removes free iron and ferrous contamination from metal surfaces to prevent rust.
