When creating advanced GTEs, one of the most important tasks is to increase the heat resistance of GTE blades. One of the basic methods of increasing the heat resistance of blades is application of special coatings. The paper deals with the results of research of Ti-Al-Si-Cr-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-Si-Cr-N based fusions were taken: conglomerate coatings with different Cr-Ti priority. The analysis of the oxidation process of surfaces in the range of 700-850 ºC with the use of scanning electron microscopy was performed and the key features of the coating fracture process under high-temperature oxidation conditions were identified. The conducted research resulted in the creation of conglomerate coatings with a maximum heat resistance increase efficiency of up to 57 times. Optimum Cr-Ti ratios for obtaining coatings with maximum high-temperature oxidation resistance were determined.
