摘要
用硅酸盐体系电解液进行铝合金微弧氧化时,氧化膜表面出现白色斑点状物,影响零件质量和外观,对这种白色斑点状物进行EDS和XRD成分测试,同时还对形成原因进行分析。结果表明,白色斑点状物是由SiO2聚集而成。
When micro-arc oxidation coatings were formed on aluminum alloy in silicate system electrolyte, white spots often appear on the coating, and the quality and appearance of work piece will be impaired. The composition of the white spots was analyzed by EDS and XRD. It is found that the white spots is SiO2. Furthermore, the formation reason was analyzed.
