EFFECTS OF ANODIZING PARAMETERS ON CORROSION RESISTANCE OF ANODIZED ALUMINUM
工艺参数对Al合金阳极氧化膜腐蚀行为的影响

The influences of anodizing parameters on microstucture,morphology and corrosion resistance of anodized oxide films of LC4 Al alloy in NaCl solution were investigated by means of SEM and potentiodynamic polarization method.Corrosion mechanism of the anodized film was discussed,and an optimized anodizing technique was suggested to improve the corrosion resistance of the film.
