Adhesion and impact wear resistance of TiC-based coatings prepared by DCMS and HiMIPS

Popis výsledku v původním jazyce

This paper is focused on study of the adhesion and the dynamic impact wear of the nanocomposite nc-TiC/a-C:H coatings prepared by hybrid PVD-PECVD process. Two series of coatings with different amount of carbon were deposited on the cemented tungsten carbide substrates by the DC Magnetron Sputtering (DCMS) and the High Power Impulse Magnetron Sputtering (HiPIMS) processes. Series of the DCMS and HiPIMS prepared coatings behaved differently. The HiPIMS prepared coatings exhibited increase oh the adhesion with increasing carbon content. On the other hand, dependence of the adhesion on the total carbon content of the DCMS prepared coatings exhibited local maximum. Dynamic impact testing revealed different response of the DSMD and HiPIMS prepared coatings on dynamic impact load. The adhesion and the impact wear behaviour depended on mechanical properties of the coatings such as a H/E and H3/E2 ratio and on the coatings surface morphology.
