摘　　要：针对目前铝合金零件局部硬质阳极氧化的工艺保护较为复杂,提出了一种容易操作的零件局部硬质阳极氧化的保护方法。试验表明,硬质阳极氧化后铬酸阳极化膜层的耐蚀性能良好。As the protection for Al alloy parts was very complex before the hard anodizing, the process parameters for the chromate acid anodizing coating as maskant were studied, and salt spray testing for the chromate acid anodizing coating after the hard anodizing was performed. An easy protection method before the hard anodizing was developed.
