The paper deals with the results of research of Ti-Al-N based thin heat resistant ion-plasma coatings for titan alloy-based parts of a gas turbine engine (GTE). To carry out the research, three Ti-Al-N based fusions were taken: conglomerate, intermetallic and nitride. The analysis of oxidation process of surfaces in the range of 500° - 825°C with the use of scanning electron microscopy was performed and the key features of coatings fracture process under high-temperature oxidation conditions were identified.
