Environmental protection and worker safety measures against hard chrome plating are increasing and leading many industries to adopt alternatives. HVOF thermal spray technology for applications of tungsten carbide based coatings have proved to be more environmentally friendly and effective than hard chrome. In this study, the results of wear tests for WG-12 percent Co sprayed coatings deposited onto AFNOR 25CD4 low carbon steel are compared to those for hard chrome. It was shown that WG-12 percent Co coatings exhibit the adequate tribological properties compared to those of electrodeposited hard chrome.
