Tribological analysis of cooling tank assisted hybrid friction stir welded 6061 aluminum alloy

Abstract:In the present work, the friction stir welding of aluminum alloy was done on the hybrid storage tank-assisted fixture at the Vertical Milling Centre. The three different storage media were used as air, water, and coolant. This study aimed to examine the effect of the cooling media in the hybrid fixture on the wear, coefficient of friction, hardness, and worn surface. The tool of mild steel was used for the welding process, and the wear of the tool was also examined for a better recommendation of tool material. In the FSW of the coolant-type welding process, it was found that the least wear was obtained at the different welding conditions. The higher rotational speed welded FSW joint increases the wear. The coefficient of friction exceeds the base material at 900 rpm in the FSW-W type joint. The average value of friction force at 500 rpm and 1000m sliding distance was 3N FSW air (FSW-A) and 5N base material. The average value of FF at 700 rpm and 1000m sliding distance was 1N FSW-A and 6 N for base material. The FF at 900 rpm was 5N FSW water type (FSW-W) and 1 N for FSW -A.Keywords: ICFSW-AICFSW-WICFSW-CwearDisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).
