Abstract
For the sake of improving the corrosion resistance of blue passivating film,a trivalent chromium blue passivant with high corrosion-resistance and a method of protective top layer with high performance were developed by experiments.When the thickness of zinc coating was more than 8 μm,both of the blue passivation process could pass 120 h NSS test.
