摘　　要：重点研究了Ni-P化学镀层和复合镀层在冲击振动载荷作用下磨损机制和磨损形态及其与镀层组织和耐磨性的关系。结果表明,振动磨损条件下的磨损形态随热处理温度的升高,由镀态时的犁沟和界面剥落逐步转变为单一细小的犁沟,即属于典型的微切削机制;第二项粒子、稀土元素(RE)对镀层的磨损机制和耐磨性也有较大提高。The wear mechanism and wear shape of Ni-P electroless plating and composite plating under the action of impact vibration load, and their relations with plating structure and wear resistance were emphatically studied. The result shows that the wear shape gradually became single and thin furrows from the furrows and boundary flake off in plating condition with the increase of heat treatment temperature under the vibration wear condition, i. e, typical micro-cutting mechanism. The second particles and rare earth also raised the wear mechanism and wear resistance.
