| 摘 要： | 采用真空热压烧结工艺制备了Ti3SiC2和Ti3SiC2-Al2O3复合材料,考察了其与GCr15钢球配副在无润滑条件、去离子水和乙醇介质中的摩擦磨损性能.研究结果表明:在无润滑条件和去离子水中,2种摩擦副的摩擦学性能较差;在乙醇中,2种摩擦副均表现出优异的摩擦学性能;从无润滑条件到去离子水和乙醇介质中,2种摩擦副的磨损机理受从钢球到盘的单向转移以及摩擦氧化控制.与单一Ti3SiC2材料相比,Ti3SiC2-Al2O3复合材料具有更好的摩擦学性能.

| Abstract: | Ti3SiC2 and Ti3SiC2-Al2O3 composites were prepared by hot pressing in vacuum. The tribological properties of the two materials in sliding against a GCr15 steel ball in dry sliding, deionized water and ethanol were investigated. The two tribo-couples exhibited poor tribological properties in dry sliding and deionized water but good tribological properties in ethanol. The wear mechanisms of the two tribo-couples were controlled by unidirectional transfer from GCr15 steel ball to the worn surfaces of Ti3SiC2 and Ti3SiC2-Al2O3 composite as well as tribo-oxidation. Ti3SiC2-Al2O3 composite showed improved tribological property as compared with monolithic Ti3SiC2. |
