In this study, WC-CoCr cermet coatings are deposited by HVOF spraying and their microstructure, hardness, and cavitation behavior are assessed. The coatings exhibit better cavitation resistance than stainless steel with an erosion mechanism that leaves wrinkles and craters that correspond to specific erosion stages.Read More
