摘　　要：通过化学成分、导电率分析、金相显微组织观察及SEM/EDS等方法,对6082-T6零部件硬质阳极氧化品进行了分析研究.结果表明,产生硬质阳极氧化品盐雾试验不过关的原因是零部件有粗大杂质存在,这些粗大杂质颗粒在阳极预处理过程掉落或残留,产生氧化膜缺陷,从而导致盐雾测试不合格.The hard anodized products of 6082-T6 parts were analyzed by means of chemical composition, conductivity, microstruc. ture and SEM/EDS. The results show that the reason for the failure of salt spray test of hard anodized products is the presence of coarse impurities in the parts, which fall off or remain in the process of anode pretreatment, leading to defects of oxidation film and thus unqualified salt spray test.
