摘　　要：采用直流电沉积方法在镀液中加入有机添加剂制备出镍钴纳米合金镀层.采用扫描电镜分析了镀层的微观形貌及晶粒尺寸,研究了电流密度、pH等工艺条件以及有机添加剂和稀土钐对镀层中钴含量的影响,采用加热实验法测定了镀层的结合力.实验结果表明,镀层表面致密、平整,结合性能优良.Electrodeposited of nickel-cobalt nanocrystalline alloys were obtained by direct current with addition of organic additives in the bath under. Morphology and grain size of alloys were analysed by SEM. The effect of current density, pH value, organic additives and rare earth samarium on cobalt content were studied, the adhesion of the film were tested by heating. The test results show that the nickel-cobalt film obtained has fine and leveled surface and good adhension.
