The composition, structure and corrosion resistance of Ti(Ⅳ) compound modified passivating film formed from low concentration chromate containing solution are studied by means of SEM,?EDX? XRD and corrosion measurements. Practice and theory show that the passivating film is kind of composite film consisting of CrOOH, ZnCrO 4, TiO 2,Cr 2O 3 and TiOSO 4 because it is formed bv chromatizins and hydrolysis depositione reaction. Corrosion resistance of this kind of passivating film is 3~4 times… CONTINUE READING
