Investigation on Erosion Resistance of WC-Co-Cr Coatings

The erosion behavior of three high velocity oxy-fuel/air-fuel (HVOF/HVAF) sprayed WC-Co-Cr coatings has been investigated using Al2O3 as erodent at impingement angles of 15° and 90° and impact velocity of 30 m/s. The results indicated that the mixed removal of Co-Cr binder and WC cuboids, plastic de...
