Abstract—The possibility of using Ti–Al–N, Ti–Al–Ni–N, Ti–Cr–Ni–N, and Ti–Cr–Ni–Mo–N coatings deposited by ion-plasma vacuum-arc deposition as protective on products made of steel 20Kh13, working in a friction pair with carbon fiber plastic of the UGET grade in contact with seawater, has been investigated. An improvement in the resistance properties of a steel surface is shown when using coatings of the Ti–Al–Ni–N, Ti–Cr–Ni—N, and Ti–Cr–Ni–Mo–N systems. And the products without or with Ti–Al–N coating showed high friction wear rates (109.21 × 10–5 and 19.24 × 10–5 mm3/(N m), respectively), as well as active oxidation during electrochemical tests under conditions of interaction with a medium simulating seawater (3% NaCl solution). Specimens with Ti–Al–Ni–N, Ti–Cr–Ni–N, and Ti–Cr–Ni–Mo–N coatings did not demonstrate significant wear during friction when paired with carbon fiber. Electrochemical tests of the coatings showed that they were self-passivated and there was no pitting on the surface of the coated specimens. On the basis of the analysis of the data obtained, a conclusion was made about the high efficiency of the studied coatings as protective for work in contact with seawater. [ABSTRACT FROM AUTHOR] |
