用电化学极化和扫描电镜(SEM)观察法,研究了电流密 度、氧化时间和氧化温度等工艺参数对LC4铝合金阳极氧化膜的厚度、显微形貌和在NaCl溶 液中耐蚀性的影响，讨论了影响氧化膜耐蚀性的机制，提出了提高耐蚀性的最佳阳极氧化工 艺参数.
The influences of anodizing parameters on microstuct ure,morphology and corrosion resistance of anodized oxide films of LC4 Al alloy in NaCl solution were investigated by means of SEM and potentiodynamic polar ization method.Corrosion mechanism of the anodized film was discussed,and an opt imized anodizing technique was suggested to improve the corrosion resistance of the film.
