Pickling & Passivation | Astro Pak
Without pickling and/or passivation, stainless steel is subject to corrosion in service which can lead to costly quality issues. What is the Difference Between Pickling and Passivation? Although pickling and passivation both involve using acids to treat the surface of metals, there are some very distinct differences between the two processes. ... Return Document

Phosphate Conversion Coating - Wikipedia
Phosphate coatings are used on steel parts for corrosion resistance, lubricity, or as a foundation for subsequent coatings or painting. It serves as a conversion coating in which a dilute solution of phosphoric acid and phosphate salts is applied via spraying or immersion and chemically reacts with the surface of the part being coated to form a layer of insoluble, crystalline phosphates. ...
