Structure and properties of the Ti + Ti(C,N) coatings obtained in the PVD process on sintered high speed steel

Abstract The paper presents investigation results of the effect of deposition parameters on structure and mechanical properties of the two-layer Ti + Ti(C,N) coatings obtained by magnetron sputtering in the vacuum furnace onto the ASP 30 sintered high speed steel. Effect of sputtering parameters on chemical and phase compositions, thickness, microhardness, Young's modulus and adhesion of coatings to the substrate material was evaluated. The characteristic structure and surface topography of the analysed coatings are presented.
