摘　　要：研究了机械搅拌法制备的半固态B4C/Y112复合材料在不同载荷下的磨损性能。采用SEM对磨损面和磨屑显微组织进行了观察与分析,讨论了不同质量分数的B4C颗粒对磨损机制的影响。结果表明,基体和复合材料磨损质量损失都是随着载荷的增加而增加,磨损质量损失随B4C颗粒含量增加而减少。随着载荷增加,材料从轻微磨损向严重磨损转变。总体上讲,复合材料比基体的耐磨性好。The wear properties of semi-solid B4C/Y112 composites prepared by mechanical stirring were studied under different load. The wear faces and chip microstructures of the composites were observed and analyzed using SEM, and wear mechanism was discussed under different mass fractions of B4C particles. The results show that the loss of wear mass in matrix and composite material increases as load increases, and decreases as the ＇content of B4C increases. Material transforms from mild to severe wear abrasion as load increases. Generally speaking, the wear properties of the composite is better than that of matrix.
