Durability and tribological properties of thermally sprayed wc cermet coating under lubricated rolling-sliding contact

Durability and tribological properties of thermally sprayed WC-Cr-Ni cermet coating were investigated experimentally under lubricated rolling with sliding contact conditions. By means of the high energy type flame spraying (Hi-HVOF) method, the coating was formed onto the axially and circumferent...
