Abstract
Ni-P-PTFE composite coating was prepared by electroless plating based on the Ni-P coating technology. The effects of surfactant and PTFE content on the binding force, hardness, friction coefficient, wear rate and content of PTFE particles of the composite coating was investigated. In addition, the tribological behaviors of composite coating were discussed. The surface morphology and microstructures of composite coating were analyzed using scanning electron microscopy (SEM) and X-ray diffraction (XRD), and the wear mechanism of composite coating was analyzed by using the MRH-3 friction and wear tester. The results indicated that the Ni-P-PTFE composite coating prepared under the optimum process condition exhibited excellent friction properties, and the wear mechanism is manifested as adhesion and slight grain-abrasion during the abrasion.
