| 摘 要： | 采用SRV摩擦磨损试验机评价了Ti3AlC2在干摩擦以及水和乙醇润滑条件下的摩擦磨损性能，分析了Ti3AlC2磨损表面形貌和化学组成，简要讨论了水和乙醇的黏度对其润滑性能的影响。结果表明：在干摩擦和水润滑条件下，Ti3AlC2/Si3N4、Ti3AlC2/Al2O3和Ti3AlC2/GCr15钢3种摩擦副的耐磨性能较差，而在乙醇润滑条件下，由于乙醇可抑制Ti3AlC2的晶粒拔出、断裂以及偶件材料向Ti3AlC2的转移，从而导致3种摩擦副的耐磨性能优异。 |

| Abstract: | The friction and wear behavior of bulk Ti3AlC2 under dry sliding and lubrication of water and ethanol was evaluated by using an SRV oscillating friction and wear tester. The morphology and chemical composition of the worn surfaces of Ti3AlC2 and counterparts were analyzed by means of scanning electron microscopy and energy dispersive spectrometry. The relationship between the viscosity and lubricity of water and ethanol was briefed. Results show that Ti3AlC2/Si3N4, Ti3AlC2/Al2O3, and Ti3AlC2/GCr15 pairs exhibited poor wear resistance under dry sliding and water lubricated condition, but they had excellent wear resistance and lowered friction coefficient as well under ethanol lubricated condition. The reason might lie in that the pullout and fracture of Ti3AlC2 grains and transfer of the counterparts to Ti3AlC2 were greatly inhibited under the lubrication of ethanol. |
