| Abstract | 采用滑动磨损试验方法测试了NiAl-Cr（Mo）-CrxSy自润滑复合材料与SiC陶瓷配副在110～960℃的摩擦磨损特性.结果表明：200～400℃,纳米CrxSy晶粒在复合材料摩擦表面形成较完整的润滑膜,产生自润滑性能;700～900℃,复合材料摩擦表面生成了1～3μm厚、完整的玻璃陶瓷润滑膜,产生了自润滑耐磨性能.2种润滑膜材料均可向SiC表面转移,消除了复合材料/SiC的摩擦状态.随着温度的升高,2种润滑膜材料的强度降低,SiC微凸体压入润滑膜,导致润滑膜的剥落加剧,复合材料的摩擦系数与磨损率升高. |
| Other Abstract | The wear behaviors of NiAl-Cr（Mo）-CrxSy self-lubricating composite against SiC ceramic under dry sliding intented temperature range from 110 to 960 ℃ were investigated on a pin-on-disc test rig.The results reveal that between 200℃ and 400℃,CrxSy-type eutectic compound form a relatively intact lubricant film composed of nano-CrxSy-type eutectic compound overlays the friction surface.The composite exhibit excellent permanent self-lubricating properties in the temperature range of 200～400 ℃.The composite exhibit excellent permanent self-lubricating properties and better anti-wear properties in the temperature range of 700～900 ℃,that is attributed to the formation of glass-ceramic lubricant film with the thickness of 1～3 μm.Wear type of tested materials/SiC is eliminated,which is lead by the transfer the lubricant film to the surface of SiC.With the increasing of tested temperature the friction coefficient and wear rate become higher,which contribute to the decreasing of strength and the spallation owing to the incursion SiC particles for the self-lubricant film. |
