Apr 30, 2014 The effect of the anodizing process parameters and the influence of (Mg 2 Si) phase on the appearance of the anodized AA6063 aluminum alloy have been investigated. It was found that (Mg 2 Si) phase was preferentially oxidized at low anodizing voltages and the selective oxidation of (Mg 2 Si) phase resulted in the development of a rough alloy/film interface and the incorporation of ...

aluminum or aluminum alloy to be sandblasted. For example, alloy 1100, which contains 99% A1, provides a transparent anodic finish; alloys rich in manganese, silicon, and copper, on the other hand, are colored when anodized. Alloy segrega- tion can occur in high-magnesium alloys, and pitting will result unless special pretreatments are used.
