Method Study of Improving Surface Corrosion Resistance of 6063 Aluminum Alloy

Abstract:

The method to improving surface corrosion resistance of 6063 aluminum alloy was studied, and the mechanism of surface corrosion resistanc was discussed in theory. The results indicate that the adjustment of chemical composition is of advantage to corrosion resistance of the alloy, its property is better as Mg, Si mass ratio at about 1.55. The necessary homogenizing treatment of cast ingot subserves corrosion resistanc of aluminum extrusion, and the cast ingot should be cooled quickly after heat treatment. Significant effect of extrusion technology on erosive property is observed from aluminum alloy, aluminum extrusion has good corrosion resistance when outlet temperature is at about 510 degree centigrade.
