Mechanical Properties and Tribological Performance of TiN/VCN Multilayers
Source abstract
Abstract
Monolithic TiN, VCN films and TiN/VCN nano-multilayer films with different modulation periods were prepared by magnetron sputtering. Microstructures, mechanical properties and friction properties at room and high temperature of these films were investigated by X-ray diffraction (XRD), nano-indentation, and CSM high tem- perature ball-on-disc tribometer. The results show that the TiN/VCN multilayer films are mainly nanocrystalline with δ-NaCl fcc structure. Maximum hardness of TiN/VCN multilayer films is 28.71 GPa, about 23% higher than the value calculated by the rule of mixtures. Based on these data, a mechanism of the superhardness in this system is proposed. Friction coefficients of TiN/VCN multilayers are similar to that of TiN films at room temperature, but lower than that of TiN films when testing temperature is increased to 700 . ℃ Wear rates of TiN/VCN multilayers at
