Abstract: In this paper, the effect of operating variables such as abrasive particle size, slurry concentration, speed of rotation and slurry bath temperature on Abrasive Slurry Wear (ASW) behaviour of cobalt-based alloy (stellite) surface produced by Plasma Transferred Arc (PTA) hardfacing process has been analysed. Of the four variables considered in this investigation, it is found that the slurry concentration has a predominant effect on wear rate of hardfaced surface compared with other variables. Both experimental and mathematical investigations show that wear resistance of hardfaced stellite surface is three times better than that of the substrate (carbon steel).
