摘　　要：以铁片作为基材,采用电镀工艺制备Ni-ZrO2纳米复合镀层。研究了温度、pH值、时间及ZrO2的质量浓度对复合镀层性能的影响。通过实验得出最佳的工艺参数为:ZrO21.5g/L,pH值4～5,50℃,60min。采用扫描电子显微镜观察复合镀层的微观形貌,并通过XRD分析其相组织成分。结果表明:复合镀层表面光亮,微粒均匀、细小;其相组织成分主要为Ni,ZrO2和Ni-ZrO2。With iron plate as substrate,a Ni-ZrO2nanocomposite coating was prepared by electroplating process.The effects of temperature,pH value,time and mass concentration of zirconia on the performance of the composite coating were investigated.The optimal technological data obtained through experiment are：ZrO21.5g/L,pH 4～5,temperature 50 ℃,time 60min.The microstructure of the composite coating was observed by using scanning electron microscope,and its phase composition was analyzed by XRD.The results show that the composite coating has a bright surface,even and fine in particle size;its main phase components are Ni,ZrO2and Ni-ZrO2.
