EN Purpose: The following article demonstrates the characteristics of the materials applied as parts of aircraft engine turbines and the stationary gas turbines. The principal technologies for manufacturing the heat resistant coatings and the erosion and corrosion resistant coatings were characterized. Sample applications for the aforementioned coatings are presented: on turbine blades, compressor blades and on parts of combustion chambers of aircraft engines. Design/methodology/approach: The nickel-based alloys were characterized. The following methods of depositing diffusion aluminide coatings were described: pack cementation, out of pack and CVD (chemical vapour deposition). The properties of thermal barrier coatings obtained by thermal spraying and physical vapour deposition (PVD) were presented. Findings: : The structures of aluminide and platinum modified aluminide coatings, which displayed higher heat resistance during the cyclic oxidation test, were presented. The structure of TBC coatings was described as well. During aircraft engine tests, the compressor blades with multilayer type Cr/CrN coatings exhibited higher wear resistance than the coatings covered with Ti/TiN. Research limitations/implications: The aluminide coatings were deposited on nickel-based superalloys, which are typically used to manufacture turbine blades for aircraft engines. The multilayer nitride coatings were produced by Arc-PVD method. Practical implications: All the described technologies and coatings find applications on parts of aircraft engines. Originality/value: The presented advanced technologies of manufacturing protective coatings on the parts of aircraft engines were developed by the authors of the following study as parts of their planned scientific research, research projects, and purpose projects.
