摘要(Abstract)：

为考察TiB2含量对微波烧结TiB2/Cu复合材料组织和磨损性能的影响,采用微波烧结技术制备了含TiB2体积分数不同的TiB2/Cu复合材料。测试了试样的密度和显微硬度,分析了试样的组织。应用摩擦磨损试验机测试了试样在不同载荷下的磨损性能,并应用扫描电镜(配能谱仪)观察和分析了试样磨损面形貌和成分。结果表明:随TiB2含量增加,试样中孪晶数量减少;晶粒反而随TiB2含量增加而增大,其长大方式是晶界绕过团聚颗粒后进行合并而长大;试样的耐磨性能随TiB2含量增加而显著提高,其主要的磨损机制也由粘着磨损逐渐向磨粒磨损转变。

关键词(KeyWords)： 微波烧结;铜基复合材料;TiB2颗粒;微观组织;磨损
