Passivation
Passivation, in physical chemistry and engineering, refers to removing the free iron from stainless steel so it becomes “passive,” that is, less readily affected or corroded by the environment. This is accomplished by submersing the stainless-steel part in a solution containing either nitric acid, nitric acid with sodium dichromate, or citric acid at all different temperatures and concentrations. Removing the surface iron encourages the formation of a natural chromium layer, which acts as the corrosion resistant aspect of passivation. Aerotech performs passive formation under various military and prime specs such as QQ-P-35, AMS-2700, and ASTM-A967 in addition to others. We have in-house testing capabilities via 24-hour humidity testing as well as copper sulfate.
Relevant Specifications:
AMS2700 – Passivation of Corrosion Resistant Steels
QQ-P-35C – Federal Specification: Passivation Treatments for Corrosion-Resistant Steel
ASTM A967-01 – Standard Specification for Chemical Passivation Treatments for Stainless Steel Parts
