摘要：
Four iron-based braking materials are developed via powder metallurgy technology based on the experiments of components and technology parameter. Mechanical property and friction and wear property are tested. The material which is prospected to use for high-speed train is obtained with the well mechanical property and the property of friction coefficient of 0.31, wear rate of 2.2μm once and friction stability of 88.9%. The microstructure is observed and the relationship between the property and the microstructure is discussed. Three key factors influencing on tribological characteristics of the braking lining are put forward.
