Abstract

The structural-phase state was investigated and the load was determined at which the tearing of CrN and TiCrN coatings formed by vacuum arc deposition on substrates of 12X18H10T steel and Zr2,5%Nb alloy occurs. It is established that the TiCrN coating has a single-phase structure (Ti,Cr)N with a face-centered cubic crystal lattice, and the CrN coating consists of chromium nitride CrN. The TiCrN coating, due to its alloying with Ti atoms, has a higher tearing load compared to the CrN coating. At the same time, in the TiCrN coating, the tearing load from the substrate made of Zr2,5%Nb alloy is ≈2 times greater than that from the substrate made of steel 12X18H10T. It is shown that the CrN coating, on the contrary, can withstand heavy loads before tearing from a substrate of 12X18H10T steel than from a Zr2,5%Nb alloy.
