| Abstract: | Using single factor experiments, the experimental conditions of magnesium alloy preparation''s cerium nitrate conversion film were studied and found under certain conditions, cerium nitrate could generate macro-dense conversion coating on the surface of magnesium alloy. By immersion hydrogen in 3.5% NaCl solution, polarization curves (Tafel), and scanning electron microscopy(SEM), the conversion coating was tested. The results show that at pH=3, hydrogen peroxide concentration= 4 mL/ L, the conversion film is better. |
