摘要：

The tribological stability of particle reinforced aluminum matrix composites in braking was studied. Considering the requirements of the intention of present transportation field, high braking pressure and high initial braking rotating speed, as well as different reinforcement volume fractions were selected. The results indicate that under a systematic comparison with traditional braking material of cast iron, SIC particulate reinforced aluminum material composites (PRAMC) can retain stable friction coefficient in various braking pressures and rotating speeds. Even in a concrete course of braking, PRAMC can also maintain friction coefficient with little fluctuation. The existence of a uniform mass transfer layer adhering to the contact surface is an important prerequisite for maintaining a stable friction coefficient.
