电镀法制备晶态Ni-W合金镀层摩擦与磨损性能
Fraction and wear properties of crystalline Ni-W alloy coating prepared by electroplating
摘要
Abstract
Ni-W alloy coating was prepared on the N80 steel surface with electroplating method, its coating coating was changed from amorphous structure into crystalline structure after the heat treatment of 500 癈, and the elements spectrums and phase compositions were analyzed by SEM, EDS and XRD, respectively. The sliding wear properties of Ni-W coating were researched; its friction coefficient was tested; the surface morphologies after wear were observed by SEM, and the wear mechanism was discussed. The results show that the crystalline Ni-W coating is composed of Ni-based solid solution, its surface tnicrohardness is 1 100, the roughness is 454.41 run, the friction coefficient is about 0.52, Ni-W coating has strong anti-wear ability, the coating surface after wear mainly presents minor scrape phenomenon, the particle attrition is mainly caused by coating spalling, and the wear rate increases obviously.关键词
