N31型磷酸盐激光玻璃的摩擦磨损性能研究

Friction and Wear Behaviors of N31 Phosphate Laser Glass

  • 摘要: 在Rtec-MFT3000多功能摩擦磨损试验机上采用硅酸盐玻璃球作为对摩副,研究了0.2~2 N的载荷条件下N31型磷酸盐激光玻璃的摩擦磨损性能,着重讨论了载荷对该玻璃摩擦磨损性能的影响.结果显示:稳定磨损阶段的摩擦系数随载荷的增加而减小,且载荷越大摩擦系数达到稳定所需的时间越短.随着载荷的增加,N31型磷酸盐激光玻璃的磨损体积先急剧增加后缓慢增加,同时磨损机理经历从磨粒磨损为主到磨粒磨损和裂纹滋生并存最后到脆性剥落为主的转变过程.而硅酸盐玻璃球的磨损体积在给定载荷范围内随载荷的增加保持线性增加,且在所有试验载荷下的磨损机理均以磨粒磨损为主.在目前试验条件下N31型磷酸盐玻璃表面磨损区域未发生可被EDS检测到的明显的摩擦化学反应,磨屑成分为对摩副两种材料的混合体.

     

    Abstract: Using a Rtec-MFT3000 universal tribometer, the friction and wear behaviors of N31 phosphate laser glass against silicate glass ball were investigated in the load range of 0.2 to 2 N, and the influences of load on the friction and wear behaviors were discussed emphatically. Experimental results indicate that increasing load decreased the friction coefficient in stable stage. A shorter running-in time was observed under a higher load. The wear volume of N31 phosphate laser glass first increased sharply and then slowly with increase in load. The wear mechanism transition from abrasive wear to the combined action of abrasive wear and crack initiation, and finally to material brittle exfoliation was observed by increasing the load. However, the wear volume of silicate glass ball increased linearly with increasing load and the wear mechanism was abrasive wear. The tribochemical reaction is not obvious in the wear tracks detected by EDS in phosphate laser glass and the wear debris was the mixture of the materials from the tribo-pair.
