Influence of Cu Content on the Structure, Mechanical, Friction and Wear Properties of VCN–Cu Films

VCN–Cu films with different Cu contents were deposited by reactive magnetron sputtering technique. The films were evaluated in terms of their microstructure, elemental composition, mechanical, and tribological properties by X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDS), high re...
