Passivation of Stainless Steel
Passivation removes ferrous surface contamination created when stainless steel is machined and fabricated. These contaminants can result in premature corrosion that could ultimately damage the part. In addition to surface cleaning, passivation forms a thin, transparent oxide coating that fights oxidation.
Passivation is performed with a thorough cleaning and then the immersion in an acid bath. A failure in process control can mean extreme pitting, etching, or even catastrophic failure and total dissolution of the entire component. A range of variables are factored into the calculations:
DIXIE has implemented the careful process control essential for a quality passivation of stainless steel. DIXIE's passivation process meets the requirements of:
