Effects of Metal Matrix Composition on the Pre-Sintering Process of Cu-Based Metallic Friction Materials

Abstract:

This study investigates the effect of the metal matrix composition of the friction material on the pre-sintering process through a simulation experiment on the Sprinkle sintering process. No segregation in the pre-sintered microstructure of the free-deposited friction material powder and no cracks are observed at the interface with the steel plate. In the case of a brass composition containing Zn and trace elements having relatively high vapor pressure, expansion occurs due to the volatilization of the composition elements during pre-sintering. On the contrary, in the case of bronze-based powder, the effect is insignificant. Therefore, when the friction material is manufactured using the sprinkle sintering method, the matrix composition must be selected in consideration of the volatilization effect of the metal matrix element.
