Description
Summary:The work presents the investigation results of the effect of coating process parameters structure, erosion resistance, and mechanical properties of the two-layer Ti + TiN, Ti + Ti(C x N 1− x ), and Ti + TiC coatings obtained using magnetron sputtering in the chamber with the controlled temperature on the substrate from the ASP 30 sintered high-speed steel. Test results of the mechanical properties tests of the obtained coatings are presented, depending on the specimen distance from the magnetron disk, working atmosphere, and chamber temperature. The effect was evaluated of the vapour deposition parameters on micro-hardness, adhesion to the substrate material, and erosion resistance of the coatings. Characteristic structure and surface topography of the mentioned coatings are presented.
