研究了用XD法制备的ZL201／TiB2原位自生复合材料的组织与平滑动磨损行为经175℃时效后，ZL201／TiB2的组织由α-Al、θ”、θ’相及原位自生的亚微米级TiB2颗粒构成TiB2颗粒大大提高了材料的硬度和耐磨性在本试验条件下，ZL201／TiB2的磨损机制是粘着磨损和熔化磨损随滑动距离增加，主导磨损机制由粘着磨损向熔化磨损过渡，磨损速度迅速增大 The microstructure and smooth sliding wear behavior of ZL201 / TiB2 in situ composites prepared by XD method were investigated by means of α-Al, θ ", θ ’phase and in-situ spontaneous TiB2 particles on the order of TiB2 particles greatly improve the hardness and wear resistance of the material Under the experimental conditions, the wear mechanism of ZL201 / TiB2 is that the adhesion wear and melting wear increase with the sliding distance, and the dominant wear mechanism transition from adhesive wear to melt wear , The wear rate increases rapidly
