摘要
通过喷射电沉积的方法制备了高钴含量的钴镍合金镀层,并研究了添加剂糖精钠对镀层表面形貌、组织成分、微观结构、硬度及摩擦磨损性能的影响。结果表明,糖精钠的添加并不影响镀层的成分及结构,但其可以使Co-Ni合金镀层的组织得到细化,进而增强镀层性能。当糖精钠添加量为1g/L可以使镀层力学性能得到显著增强,此时镀层硬度达565 HV,耐磨性最好。
The cobalt-nickel alloy coating with high cobalt content was prepared by spray electrodeposition.The effects of sodium saccharin on the surface morphology,composition,microstructure,hardness and friction and wear properties of the coating were investigated.The results show that the addition of sodium saccharin does not affect the composition and structure of the coating,but it can refine the microstructure of the Co-Ni alloy coating and enhance the coating performance.When the amount of sodium saccharin is 1g/L,the mechanical properties of the coating can be significantly enhanced.At this time,the hardness of the coating is 565 HV and the wear resistance is the best.
