Influence of the surface roughness of the C55 steel on its tribological properties after application of the WC / C coating

Abstract Influence of the surface roughness (rough grinding, grinding, polishing) of stainless steel C55 on its tribological properties, after application of the WC/C coating, is experimentally verified in this paper. Results of the tribological tests, taking into account the complexity of the surface preparation, proved that the most suitable way is applying the WC/C coating onto the ground surface of carbon steel C55.
