Abstract
The structure and tribological properties of the nitride coatings (Zr-Ti-Nb)N, (Zr-Ti-Cr-Nb)N, and (Zr-Ti-Cr-Nb-Si)N, fabricated by vacuum arc deposition have been investigated. Their elemental composition and crystal structure are characterized by EDS and SEM analyses, XPS, and X-ray diffraction. The multicomponent (Zr-Ti-Cr-Nb-Si)N and (Zr-Ti-Nb)N coatings are found to be a simple face-centered cubic (fcc) solid solution. For the coatings without Si, the structure is mainly composed of the TiN fcc phase and Cr2N trigonal modification. The (Zr-Ti-Nb)N and (Zr-Ti-Cr-Nb)N coatings provided the best adhesive strength in different conditions. The (Zr-Ti-Cr-Nb-Si)N coatings exhibited the worst adhesive strength, which may be attributed to the relative low hardness.
