Iron-based powder metallurgy friction material

Abstract

The invention discloses an iron-based powder metallurgic friction material, which consists of the following components by weight percentage: copper powder (Cu) 8 to 13 percent, molybdenum powder (Mo) 3 to 7 percent, nickel powder (Ni) 1 to 3 percent, lead powder (Pb) 2 to 6 percent, graphite (C) 9 to 14 percent, molybdenum disulfide (MoS2) 2 to 5 percent, cast stone 2 to 5 percent, silicon carbide (SiC) 1 to 4 percent, mullite (3Al2O3*2SiO2) 5 to 8 percent, and iron powder in balance. The friction material has the advantages of high friction efficiency, less wear rate and excellent high temperature performance, and is suitable for braking middle and heavy airplanes, engineering vehicles and artillery.

Description

technical field [0001] The invention relates to a friction material, in particular to an iron-based powder metallurgy friction material. Background technique [0002] The brake device is an important component necessary for various aircraft and vehicles, and the performance of the brake material directly affects the performance and safety performance of the aircraft and vehicles. [0003] At present, friction materials produced by powder metallurgy are widely used in the manufacture of various aircraft and vehicle braking devices. If the friction coefficient of the material is low, it is easy to cause slipping; if the wear rate is too high, it will reduce the service life of the brake pad; Contents of the invention [0004] In order to overcome the shortcomings of the existing friction materials such as low service life and easy burns, the present invention proposes a new type of powder metallurgy friction material, which has the characteristics of high friction efficienc...
