FIELD: aviation equipment.
SUBSTANCE: invention relates to the field of aviation engine construction and can be used in the gas turbine engines inter-rotor supports sliding bearings. Inter-rotor support sliding bearing includes the outer and the inner rings made of the titanium carbonitride and aluminum nitride based metal-ceramic material, respectively, at a given ratio of components. Rings are located inside the high and low pressure rotors shafts. Technical result: ensuring the sliding bearing rings material microhardness required level at temperatures of up to 500 °C, which allows to increase the gas turbine engine inter-rotor support sliding bearing wear resistance and durability.
EFFECT: technical result: ensuring the sliding bearing rings material microhardness required level, which allows to increase the gas turbine engine inter-rotor support sliding bearing wear resistance and durability.
