About the Process

Passivation is a chemical reaction that causes a material to be less affected by corrosion or other environmental factors. Passivation causes a micro-coating to be applied on the surface of the material by allowing the material to oxidize, then converting the oxidation to a metalophosphate. This surface is then sealed into the part using either a manganese or zinc compound.
