摘要
采用电泳沉积-化学镀两步法制备了化学镀Ni-P/纳米TiO2复合镀层,研究了电场强度、电流及电泳时间对电泳工艺的影响,确定了合适的化学镀工艺参数,用X射线衍射和扫描电镜对复合镀层的结构进行分析,测试了复合镀层的显微硬度,用甲基橙为模型反应物对复合镀层进行光催化降解实验.实验结果表明,纳米TiO2颗粒在复合镀层中分布均匀,在镀态下和经过热处理后复合镀层显微硬度均高于化学镀镍磷合金,复合镀层催化效果与纳米二氧化钛涂层相当.
In this paper,Ni-P-nanometer TiO2 composite coatings were prepared by electrophoretically deposite and electroless plating Ni-P alloy.The effect of the applied electric field strength,electric current and deposition durations on electrophoretically depositing were studied.Suitable technological parameters of electroless plating Ni-P solution were obtained.The microstructure of the composite coating was analyzed by XRD and SEM.The microhardness values of the composite coatings were tested.The methyl orange s...
