Perspective titanium alloys are successfully used in modern aviation gas turbine engines (GTE). However, their use is limited by low heat resistance at temperatures higher than 700oC.The paper deals with the results of research of Ti-Al-Si-Cr based thin (up to 10 microns) heat resistant ion-plasma coatings for titan alloy-based parts of a gas turbine engine (GTE). To carry out the research, three Ti-Al-Si-Cr based alloys with different microstructure were taken: intermetallic, conglomerate, and nitride. The analysis of surface oxidation process in the range of 700°–850°C with the use of scanning electron microscopy was performed and the key features of the coatings destruction process under high-temperature oxidation conditions were identified.
