The structure and properties of VN-VCN-VC coatings deposited by a high energy ion assisted magnetron sputtering method

Elemental and phase composition, as well as tribological characteristics (wear factor and friction coefficient) of the coatings were investigated. The chemical and structural investigations were performed by GDOES (Glow Discharge Optical Emission Spectrometry), EDX (Energy Dispersive X-ray analysis), XRD (X-ray Diffraction) and SEM (Scanning Electron Microscopy), while microhardness measurements and wear test were used to assess the coatings characteristics. The friction coefficient and the wear resistance of the coatings were evaluated by using pin on disc tests in unlubricated conditions.
