A problem of austenitic steel surface strengthening is considered. There are shown advantages and disadvantages of common low-temperature and high-temperature gas nitride hardening connected with the prevention of chromium nitride formation on the surface of products. The estimate of nitride steel phase structures on the basis of thermo-dynamic models and an experimental definition of parameters for obtaining an austenite surface alloyed with nitrogen are carried out.

The results of studies of the thermal stability of materials operating in a plasma jet at high temperatures and a sharp change in thermal loads are presented. It has been proven that the use of plasma generators with the introduction of various powder materials makes it possible to simulate the operating conditions of parts in high-temperature gas flows with heated particles. The effect of the introduced powder materials on the thermal stability of samples prepared by plasma spraying from molybdenum, as well as tungsten and tungsten-based compositions is investigated. An installation is proposed for assessing the thermal stability of composite materials and protective hardening coatings operating under high-temperature gas flows, which makes it possible to determine their erosion resistance.
