| 摘 要： | 研究了Ni-W-Co/SiC微粒复合镀层在润滑渐污条件下的滑动磨损特性，分析了载荷、滑动速度及SiC微粒质量分数对复合镀层磨损机制的影响。试验结果表明：在污染条件下，Ni-W-Co合金的磨损机制主要为显微切削和犁沟；SiC微粒复合相的主要流失形式为撞击脱落。

| Abstract: | Sliding wear speciality of Ni W Co/SiC micro partical composite plating in condition of lubricating oil pollutade is studied,the efffect of load,sliding speed and the mass fraction of SiC micro particals on wear mechanism of the composite plating is also analyzied.The result shows that,in condition of lubricating oil gradually pollutade,wear mechanism of Ni W Co alloy mainly is micro cutting and plouphing,SiC micro particals fall off because of collided. |
