<<The>> effect of Al composition on the microstructure and mechanical properties of WC-TiAlN superhard composite coating

Original language description

WC-Ti(1-x)AlxN nc-films were deposited on WC-Co and Si substrates using a multi-cathode arc ion-plating system. The microstructure and mechanical properties of the films were investigated to find out the nanostructured film growth mechanism. The microstructure of the WC-Ti(1-x)AlxN films depend on the Al concentration (x). The residual stress in WC-Ti(1-x)AlxN films was independent of the x value and measured to be approximately 6.5 GPa. The microhardness of WC-Ti(1-x)AlxN film was measured to be in therange of 38-50 GPa. So, we believe that the nanocrystalline microstructure of the film is of fundamental importance for the dramatic enhancement of film hardness.
