This document summarizes a study on WC-Co coatings produced by HVOF spray technique on stainless steel substrates. Three coatings were produced with varying WC particle size ranges. SEM analysis showed uniform distribution of WC particles in the coatings. XRD analysis identified WC and Co phases in the coatings. Hardness testing and pin-on-disc wear testing was conducted under varying loads and speeds. The coating with larger WC particle size (45-90μm) exhibited the lowest wear rate, indicating improved wear resistance with larger WC particle size. SEM of the worn surfaces showed grooves, pulled out particles and cracks formed during wear testing.
