Passivation

Passivation is a chemical treatment on metallic surfaces for cleaning and added corrosion protection. The purpose of passivation is for the removal of “free iron” and other exogenous foreign material from a metallic surface. During passivation a thin transparent oxide layer is formed on the metallic surface. This oxide layer is a protective surface film that inhibits chemical and atmospheric corrosion. Passivation is primarily applied to stainless steels and titanium; however other metals can be passivated either by chemical treatments or other means.

Here at Aotco, we  perform passivation on stainless steels, titanium, Inconel, nitronic 60.
