This paper deals with the study of dry sliding wear behaivour of plasma spray coatings on Al6061 composites. The TiO2 and Inconel coating ranging from 30% and 40% is coated with Al6061 alloy. Pin-on-disc wear testing apparatus is used for studying the wear behaviour of un-coated and coated on Al 6061 composites. The effect of wear parameters considered for this study was applied load and sliding speed. Taguchi method is employed to optimize the process parameters. L16 orthogonal array is used for conducting the wear experiments. The results showed that the addition of wear coated specimen (30% Inconel) was very minimal and lesser volumetric wear rate compared to uncoated Al6061. With increase in load the volumetric wear rate increases, while with increase in sliding speed the volumetric wear rate is decreased. The applied load is considered as the most significant parameter.
