Abstract

Joining of aluminium alloys has a wide application in automobile industries because of light weight and high specific strength. Compared to fusion welding process, friction stir welding (FSW) is widely adaptable to join aluminium and its alloy. In the FSW joint, grains are very finer in stir zone (SZ) compared to the other zones. The Chloride ion concentration, pH value and immersion time are reported to be the more influencing parameters on corrosion attack. The present work aims to identify the minimum corrosion conditions in the SZ of friction stir welded AA6061 aluminium alloys by statistical tools such as design of experiments (DoE), analysis of variance and response surface methodology (RSM). From the results, it is found that the chloride ion concentration has a greater influence on corrosion rate than the other two parameters.
