  • Characterization of hard protective coatings based on (Cr,Ta)N = Karakterizacija trdih zaščitnih prevlek na osnovi (Cr,Ta)N
    Čekada, Miha ...
    By reactive sputtering at low temperataures (200°C) harad coatings (Cr,Ta)N with two different compositions: ▫$Cr_{0,58}Ta_{0,42}N$▫ and ▫$Cr_{0,17}Ta_{0,83}N$▫ were prepared. Basic mechanical ... properties were evaluated such as Vickers microhardness, adhesion and internal stress in the coating. Among electrical properties, electrical resistivity and thermal coefficient of resistivity were measured. Crystal structure was also determined. All measurements were compared with results, obtained for chromium nitrideand tantalum nitride coatings, prepared at the same apparatus at similar conditions. Oxidation rate of the coatings was also measured. At temperatures above 800°C a protective layer of chromium oxide was detected which stops further oxidation. At lower temperatures on the other hand, no such layer forms and oxidation proceeds unrestrained.
