摘　　要：采用真空热压烧结工艺,制备3种不同WC粒度增强镍基合金复合材料。对复合材料的组织结构、性能以及干摩擦条件下的摩擦磨损性能进行研究。结果表明:干摩擦条件下,随着WC粒度的增加,复合材料的磨损失重增大,摩擦因数也增大,复合材料的磨损机制由磨粒磨损转向黏着磨损、疲劳磨损以及脆性颗粒剥落。Composite reinforced by WC particles of different size was fabricated by hot-press sintering（HP）. Structures, properties, especially the tribological properties of the composites were studied. The result shows that both the weight-loss and friction coefficient of the composites grow as the WC panicle size increasing and the wear mechanism changes from grain-abrasion to adhesion-abrasion, fatigue-abrasion and brittle rupture.
