STRATEGIC TRENDS OF DEVELOPMENT OF STRUCTURAL MATERIALS AND TECHNOLOGIES OF THEIR PROCESSING FOR MODERN AND FUTURE AIRCRAFT ENGINES

摘要

Strategic directions of development of materials and their processing technologies for the main parts of new generation GTE are determined for the period up to 2030. Modern tendencies of development of cast and wrought heat-resistant alloys are described, including nickel- and titanium-base intermetallic alloys. Characteristics of new vacuum equipment mounted at FSUE "VIAM" for melting of heat-resistant alloys and deformation of high-temperature materials under the conditions of isothermicity in air are given, as well as the results of developments in the field of ion-plasma deposition of protective high-temperature, strengthening and thermal barrier coatings on blades and other GTE parts and development of a new generation of plasma-chemical equipment. Technology of producing a wide range of superpure ultradisperse powders by the method of atomization for vacuum diffusion brazing and additive technologies has been developed.
