以硫酸镍、硫酸钴和氧化锆为主要原料,采用脉冲沉积技术在Q235钢基体表面沉积了Ni-Co-ZrO2复合镀层,利用扫描电镜、能谱仪、X射线衍射仪分别观察和表征了复合镀层的显微形貌、成分组成和相结构,并对Ni-Co-ZrO2复合镀层的显微硬度和耐磨性进行了研究.结果表明:ZrO2颗粒弥散分布于Ni-Co合金中,基体与镀层界面处无孔隙、裂纹等缺陷,镀层厚度约为60μm;镀态下Ni-Co-ZrO2复合镀层基质合金为晶态结构,主要生长晶面为Ni(111)和Co (110),XRD衍射图谱呈现出低强度、大峰宽和多晶向的相结构特征.随着镀层内ZrO2颗粒含量的增加,Ni-Co-ZrO2复合镀层的显微硬度呈现先提高后降低、磨损量先减少后增加的趋势,当ZrO2含量为20 g/L时,复合镀层的硬度最高、磨损量最少,磨痕形貌呈现出轻微磨损.
