Method for reducing friction and temperature rise of high-speed sealing contact surface of aero-generator

The invention discloses a method for reducing friction and temperature rise of a high-speed sealing contact surface of an aero-generator, and relates to the technical field of aerospace. Compared with a previous method for improving the sealing performance of the assembly, the method has the advantages that the feasibility of replacing new materials is low, the contact surface is greatly heated by heat generated by tight fit rotation and friction of the graphite sealing ring and the metal ring, the graphite sealing ring is easily softened, volatile gas is generated, a blister phenomenon occurs, and then oil leakage is caused; after grinding and repairing, the graphite sealing ring can reoccur again, the machining difficulty of the metal moving ring is large, and the graphite sealing ring is more prone to abrasion. On the premise that the material of the impregnated graphite sealing ring is not replaced and the sealing structure is not influenced, a micro-texture is processed on the surface of the impregnated
