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.
SUBSTRATES SUITABLE FOR ZINC PHOSPHATE PASSIVATION.
