Abstract: In this paper, TiN, ZrN, Ti x Zr 1-x N, Ti 1-x Al x N coatings were obtained by cathodic arc evaporation at optimal technological parameters. The corrosion properties of these coatings were investigated in 5% NaOH. The coating ZrN deposited by cathodic arc evaporation slows down the corrosion in the 5% NaOH by over 3,000 times, and the passive current – by 2,000 times. The Ti x Zr 1-x N coating has the best physico-mechanical properties: microhardness Н = 36 GPa, Young’s modulus Е = 312 GPa, elastic recovery W e = 78 %, resistance to elastic failure strain H/E = 0.12, and resistance to plastic strain H 3 /E 2 = 1.31 GPa. The Ti 1-x Al x N coating has the best wear properties: friction coefficient 0.09, counterbody wear intensity by volume 0.43•10 -8 mm 3 /Nm, coating wear intensity by volume 0.05•10 -4 mm 3 /Nm and by mass•0.03•10 -5 mg/Nm. Multilayer coating TiN-Ti x Zr 1-x N-Ti 1-x Al x N-ZrN (ZrN-top layer) has a complex of high physico-mechanical and wear properties in 5% NaOH.
