摘要
为了研究C_f浓度对Ni-P-C_f镀层摩擦学性能以及耐腐蚀性能的影响,采用摩擦磨损试验、热处理工艺以及盐雾腐蚀试验,通过SEM、XRD对复合镀层进行研究。结果表明:当碳纤维浓度为6 g/L时,该镀层中碳纤维含量最高,摩擦学性能、耐腐性能最好。Ni-P-C_f复合镀层的磨损为粘结磨损。碳纤维和热处理工艺通过第二相强化可增强镀层的摩擦学性能。Ni-P-C_f复合镀层的表面结构均匀致密,提高了电化学稳定性,从而增强了复合镀层的耐腐蚀性。
In order to study the effect of carbon fiber concentration on the tribological properties and corrosion resistance of Ni-P-Cf composite coating, adopting friction and wear test, heat treatment and salt spray test, by SEM and XRD ,the composite coating was researched. The results show that when the concentration of carbon fiber is 6 g/L, the carbon fiber content in coating is the highest, and the tribological properties and the corrosion resistance of the composite coating is the best. The wear of the coating is adhesive wear. Carbon fiber and heat treatment can significantly enhance the tribological properties of Ni-P-Cf by second phase strengthening. The surface structure of Ni-P-Cf composite coating is uniform and dense, which can improve the electrochemical stability, thus the corrosion resistance of the composite coating enhances.
