| 摘 要： | 使用Ni与纳米Cr颗粒共沉积方法制备Ni-Cr纳米复合镀层,研究了镀液中Cr颗粒浓度、搅拌强度和阴极电流密度等工艺参数对镀层中沉积Cr量的影响.结果表明:镀层中纳米Cr颗粒的复合改变了电沉积Ni的生长方向,Ni晶粒由原来沿(200)晶面取向生长,转变为沿(200)、(111)和(220)晶面均匀生长.镀层中Cr复合量越多,Ni晶粒的形核位置越多,Ni晶粒越细化.也探讨了Ni-Cr纳米复合镀的沉积机理.

| Abstract: | Novel Ni-Cr nanocomposite coatings were fabricated by composite electrodeposition of Ni and Cr nanoparticles from a nickel sulfate bath.The influence of the Cr contents in nanocomposite film was investigated by changing Cr concentration in electrolyte bath,agitation rate and current density. Surface morphologies and microstructure of Ni-Cr coatings were observed by means of SEM / EDAX, TEM and XRD.It was found that the codeposition of Cr nanoparticles disturbed the crystal growth of the nickel matrix,leadin... |
