More than half of the industrial wear situations are predominantly abrasive in nature. To withstand the extremities of such conditions, considerable strength is required on the surface layers to resist the imposed loads, in combination with suitable bulk hardness and toughness, which is required to prevent bulk failures. Due to stringent requirements on material surfaces, which is where the interactions with abrasives occur, and the emergence of new challenges in surface engineering, the present work has been undertaken to study the abrasive wear behaviour of selected engineering materials such as monolithic SG irons, stainless steels and high chromium irons (cast and heat treated), ceramics such as zirconia and alumina, and thermally sprayed tungsten carbide-cobalt (WC-Co) coatings applied by the High Velocity Air Fuel (HVAF) process, using powders from two sources.
