以Mg-AZ 91镁合金和TiC为增强体，采用无压浸渗法制备了金属基复合材料。复合材料对不同的AISI 4140，AISI 1045和H13钢磨损。在干滑动条件下，在不同的负载下的耐磨性进行了评价。化学分析表明，在测试过程中产生了与复合材料中存在的元素相对应的不同氧化物。复合材料的广义磨损机制基本上为磨粒-粘着型。在所有情况下，Mg AZ 91 E合金的耐磨性均优于MgAZ 91 E/TiCp复合材料。(C)2010爱思唯尔有限公司版权所有。
Metallic matrix composites (MMC) have been fabricated using Mg-AZ91 alloy and TiC as reinforcement by pressureless infiltration technique. The composites were worn against different AISI 4140, AISI 1045 and H13 steels. Wear resistance was evaluated under dry sliding condition at different loads. Chemical analyses have shown the creation during the test of different oxides corresponding to the elements present in the composite. Generalized wear mechanisms of the composites are basically type abrasion-adhesion. The wear resistance in all cases was better in the Mg AZ91E alloy than in the composite MgAZ91E/TiCp.
