Physical-Mechanical Properties of Superhard Nanocomposite Coatings on Base Zr-Ti-Si-N

Medžiagotyra, 2013
Hard and super hard coatings of Zr-Ti-Si-N of from 2.8 μm to 3.5 μm thickness were fabricated using a vacuum arc source with high frequency stimulation. The samples were annealed in vacuum and in air at 1200 °C. It was found that films with a high Zr and
