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 influence of C_f concentration on the tribological properties and corrosion resistance of Ni-P-C_f coatings, the friction and wear tests, heat treatment and salt spray corrosion tests were carried out. The composite coatings were studied by SEM and XRD. The results show that when the concentration of carbon fiber is 6 g / L, the content of carbon fiber in the coating is the highest, and the tribological properties and corrosion resistance are the best. Ni-P-C_f composite coating wear and tear for the bonding wear. Carbon fiber and heat treatment process by strengthening the second phase can enhance the tribological properties of the coating. Ni-P-C_f composite coating surface structure is uniform and compact, improve the electrochemical stability, thereby enhancing the composite coating corrosion resistance.
