Zinc Phosphate Passivation

ZINC PHOSPHATE PASSIVATION

Passivation is the removal of surface contaminants produced by machining and fabrication. The contaminants are potential corrosion sites which ultimately result in the deterioration of a component if not removed.

The resultant oxide film converts the surface of the previously oxide free surface to a crystalline phosphate composite.
