DEVELOPMENT OF IRON BASE BRAKING MATERIALS FOR Y7 AIRCRAFTS

According to different influences of various friction components on the friction and wear properties of materials and via the investigation and testing of the properties including friction,wear,anti-clamping by adding Cu, Ni, Mn, Mo, and C as basic components, MoS₂, BaSO₄, Sn and Ph as lubricants and SiC, Al₂O₃ and SiO₂ as friction components, the iron base braking materials for Y7 aircrafts have been successfully developed. It has been proved by simulating test on land, trial flying and airline Performance for a long time, that the materials have excellent friction and wear properties and their Performance duration can be increased by more than 3 times in comparison with that of original copper base friction materials.
