摘　　要：低共熔溶剂具有易降解、电化学窗口宽、合成简单及较低的成本等优点,被认为是最理想的绿色溶剂。以氯化胆碱-乙二醇(摩尔比为1∶2)为原料制备低共熔溶剂,以硫酸镍、钼酸钠为主盐,次磷酸钠为还原剂,在低共熔溶剂中化学镀Ni-Mo-P合金。考察了硫酸镍浓度的变化对化学镀Ni-Mo-P合金镀层的化学及物理性能影响。研究结果表明,当硫酸镍的浓度为15.0 g·L^(−1)时,沉积速率达到0.10μm·h^(−1),镀层平整致密,镀层中Mo元素含量达到最大值19.20 wt.%,该浓度下制备的镀层性能最佳。The deep eutectic solvents have the advantages of easy degradation,wide electrochemical window,simple synthesis and low cost,and are considered to be the most ideal green solvents.In this paper,the deep eutectic solvent was prepared with choline chloride and ethylene glycol(mole ratio 1∶2)as raw material.The main salt was nickel sulfate and sodium molybdate,reducing agent was sodium hypophosphate.Ni-Mo-P alloy was electroless plated in the deep eutectic solvent.The influence of the change of nickel sulfate concentration on the chemical and physical properties of electroless Ni-Mo-P alloy coatings was investigated.The results show that when the concentration of nickel sulfate is 15.0 g·L^(−1),the deposition rate reaches 0.10μm·h^(−1),the coating is flat and compact,and Mo content in the coat-ing reaches a maximum of 19.20 wt.%,the corrosion resistance of the coating prepared is the best.
