The present study focused on CrN-Cu nanocoatings composed of nano-meter grains with CrN, Cr and Cu functioning low-friction, anti-wear and heat resistance. The coatings were synthesized by hybrid PVD including metal arc source, magentron sputter source and ion-gun source. Although Cu has low hardness, the hardness of CrNCu is not declined because it was composed of below 20nm sized grains of CrN, Cr, and Cu. However, CrN-Cu had lower friction than CrN owing to Cu’s low shear strength. CrN-Cu films optimized using the Reaction Surface Method (RSM) showed the excellent tribological behavior and low coefficient of friction compared with DLC. The tribological properties of the Cr-Cu-N demonstrated superior wear resistance and low friction at normal and high temperature conditions. The CrN-Cu nanocoatings can be used for the downsizing automotive engines working at severe tribological conditions.
