摘要：随着近几十年来工业科技的大力发展，许多人工工艺流程基本被机器所取代，虽然这样促进了生产效率的提高，但是人们每年都要投入大笔的资金来用于更换或因为摩擦而受损的零件，因此科研工作者一直在寻找本身有一定的润滑性质的自润滑材料来代替传统的润滑材料。而复合电镀的诞生与发展正好为科学家们解决了这一难题，人们可以通过复合电镀得到具有特殊性质的复合镀层，镍基二硫化钼复合镀层就属于自润滑材料的一种。这篇文章主要探讨了镍基二硫化钼复合材料的制备工艺。本文研究了MoS2与Ni复合电镀沉积形成复合镀层的过程中受到的影响因素，寻找了最佳的工艺条件，结果表明，在普通镀镍溶液中，复合镀层的厚度和质量以及二硫化钼的固体微粒分布受电镀时间、电流密度、埋沙方式等因素影响，还发现在电流时间为2h，电流密度为0.25A/dm2时，所制得的复合镀层质量最佳。68782

Study on MoS2-Ni Composite Electroplating Process
Abstract: With the development of industrial science and technology in recent decades, many artificial processes have been basically replaced by machines. Although this has promoted the improvement of production efficiency, people have invested a lot of money each year to replace or because of friction and damaged parts, so the researchers have been looking for a certain degree of lubrication of its own self-lubricating material to replace the traditional lubricating materials. The formation and development of composite electroplating just for the scientists to solve this problem, people can get through the composite plating with a special nature of the composite coating, nickel-based molybdenum disulfide composite coating is a kind of self-lubricating materials. This article mainly discusses the preparation of nickel-based molybdenum disulfide composite materials. In this paper, the factors influencing the formation of MoS2 and Ni composite electroplating are studied, and the optimum process conditions are found. The results show that the thickness and mass of the composite coating and the solid of molybdenum disulfide in the ordinary nickel plating solution The distribution of microparticles was affected by the factors such as plating time, current density and burial method. It was also found that the composite coating had the best quality when the current time was 2 hours and the current density was 0.25A / dm2.
