Abstract

The present research paper covers statistical analysis of the major tribological factors affecting the dry sliding wear behavior of Tungsten Carbide (WC) and Chromium Carbide (Cr-C) coatings on plain carbon P/M steel substrate using High Velocity Oxy Flame (HVOF) Coating Technique. Experiments were conducted on pin-on-disc wear testing equipment. The various parameters related to wear such as wear rate, Coefficientof Friction of the coated Disc, Hardness and Surface Roughness were measured.In comparison, WC and Cr-C coating, WC coating has comparably good effect.
