摘　　要：对比研究了润滑油中磨粒尺寸和含量对镍基纳米Al2O3复合电刷镀层和快速镍刷镀层磨损性能的影响.结果发现,由于纳米颗粒的作用,在相同条件下纳米复合镀层的耐磨性比快速镍镀层提高了30%～50%,而且复合镀层的磨损体积随磨粒尺寸和含量的影响不如快速镍镀层显著.The wear property of nickel matrix nano-Al2O3 electro-plating composite coating and high speed nickel coating in lubricated condition containing solid particles were compared. The results show that the wear resistance of nano-composite coating is 30%-50% higher than that of high speed nickel coating due to the nano-particles effects, and the wear volume of the nano-composite coating are not influenced by the size and volume of solid particles in the lubricant so much as that of high speed nickel coating.
