| Abstract: | 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. |
