What is the process of passivation?

The passivation process is 50% nitric at 140-150 °F for 30 minutes. Every now and then we have to repassivate parts that were remachined. These parts are in the hardened condition (quenched and tempered) and they rust within a few hours of passivation. The as-cast surfaces rust worse but the machined surfaces rust also. ANNE BAIC (1990)See all results for this questionWhat is the passivation of stainless steel?Proper passivation of stainless steel with an oxidizing acid such as nitric or citric acid removes this free iron and promotes the growth of a thin, dense protective oxide layer which maximizes the corrosion resistance of the stainless steel.See all results for this questionWhat are the methods of nitric acid passivation?The various methods and types of nitric acid passivation include several heated options as well as options that include a sodium dichromate. The higher nitric acid concentration and the higher the nitric acid temperature, the more oxidizing potential the passivation chemistry has.See all results for this question
