Abstract	This work presents the results of superhard (Zr-Ti-Cr-Nb)N coatings research. Samples were fabricated by vacuum-arc deposition method (Arc-PVD). Structure, composition and properties of these coatings were studied. The study of coatings was performed using SEM, EDS and XRD. Hardness measurements and adhesion tests were provided. The coatings thickness was up to 6.2 mm. Nanocrystallites sizes ranged from 4 to 7.3 nm. Values of hardness and cohesive strength were H=43.7 GPa and LC=62.06 N respectively. The optimal conditions for coating’s deposition were found.
