摘要 采用反应烧结技术制备了Ti3SiC2陶瓷.利用环盘摩擦磨损试验机,研究了压力(栽荷)对反应烧结Ti3SiC2陶瓷的千摩擦磨损性能的影响.试验在环盘摩擦试验机上进行,以低碳钢为对摩体,温度为25℃,相对湿度为23%~25%,滑动时间为0.5h,滑动速度为0.5m/s,法向压力为20~60N.试验结果表明:随着压力的增大,Ti3SiC2陶瓷的干摩擦因数和磨损率均呈现先增加后降低趋势,干摩擦因数正压力为30N时最大,而磨损量则在压力为40N时最大.利用扫描电镜分析了压力对Ti3SiC2陶瓷的干摩擦磨损性能的影响,探讨了其摩擦磨损机理:当压力较小时,磨损以磨损表面发生流变和Ti。SiC2粒子脱落造成的磨粒磨损为主;当压力超过40N时,则以氧化膜的轻微划痕和轻微黏着磨损为主. Ti3SiC2 ceramic is prepared with reaction-sintering,whose dry friction and wear behaviours are investigated by a ring-disk tribology tester. Low carbon steel is chosen as the counterpart. The test is conducted at room temperature and relative humidity of 23-25%, the sliding speed and the normal pressure are taken as 0. 5 m/s and 20-60 N for 0. 5 h. The results show that the coefficient of friction and wear ratio of Ti3SiC2 increase first and then decrease with the increasing normal pressure. The peak values of coefficient of friction and wear ratio appear when the normal pressure gets 30 N and 40 N, respectively. The effect of normal pressure on the wear behaviours of Ti3SiC2 is analyzed by scanning device. When the pressure is low, the main wear mechanisms are found to be slight abrasive wear caused by the desquamating of Ti3SiC2 particles and rheologic behavior of worn surface; when the pressure is higher than 40 N, the main wear mechanisms are found to be slight scratch and light adhesive wear of the oxidation film.
