摘　　要：为了探讨凹坑形态与纳米碳化硅/镍基复合镀层耦合表面的磨损性能,采用激光技术和电沉积技术制备了由凹坑形态和纳米碳化硅/镍基复合镀层构成的仿生耦合表面,并进行了摩擦和磨损试验。结果表明,仿生耦合表面的磨损性能高于单纯复合镀层的磨损性能;随着磨损载荷的增加和磨损时间的延长,试样表面磨损机制由以塑性磨损为主逐渐转变成以粘着磨损、磨粒磨损为主的磨损机制。Laser and electric deposition technologies were used to fabricate bionic coupling surfaces with concave pits morphology and nickel matrix nano-sized SiC/Ni composite coatings.The tribological properties of the bionic coupling surface were investigated by friction and abrasion experiments.Experimental results show that the wear resistance of the bionic coupling surfaces is better than the surface with composite coating only.As the wear load and time increase,the tribological mechanism of the samples transforms from plastic dominance to adhere abrasion and grain abrasion dominance.
