在制动试验条件下,研究铝基复合材料的摩擦磨损性能研究结果表明;与铸铁材料相比,铝基复合材料能大大地降低摩擦表面温度,其摩擦系数可在较大载荷、较高转速下保持稳定,有利于制动性能的提高复合材料在不同摩擦试验后的磨损量与SiC含量和基体种类有关.在相同摩擦条件下,磨损量随颗粒含量增加而减少.与铸铁材料相比,它具有重量轻、导热快、摩擦系数稳定,不产生热裂,是较适宜的制动盘(毂)材料.
Under the condition of braking test, the research on the friction and wear properties of aluminum matrix composites shows that compared with cast iron, the aluminum matrix composites can greatly reduce the friction surface temperature. The friction coefficient of the aluminum matrix composites can be increased under high load, Under the same friction conditions, the amount of wear decreases with the increase of the particle content.Compared with the cast iron material, the wear resistance of the composite material after different friction test is lower than that of the cast iron material, It has a light weight, fast heat conduction, stable friction coefficient, does not produce thermal cracking, is more appropriate brake disc (hub) material.
