Performance Verification of Zinc Alloy Black Passivation Film
On the surface of zinc alloy after physical polishing,the black conversion film with strong bonding force is di-rectly formed,the crystallization is uniform and fine,and the bonding force with the matrix and the coating is firm.Evalua-tion and testing are made on passivation film bonding force,wear resistance,corrosion resistance,resistance to chlorine ammonia,coating adhesion and paint and powder coating performance of various aspects,and the results show that this black passivation film is very suitable for zinc alloy black surface coating substrate.
