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.

Abstract:: The electrophoretic Ni-P/nano-TiO2 composite coating was prepared by electrophoretic deposition-electroless plating, the effects of electric field strength, current and electrophoresis time on the electrophoresis process were studied, the appropriate electroless plating process parameters were determined, the structure of the composite coating was analyzed by X-ray diffraction and scanning electron microscopy, the microhardness of the composite coating was tested, and the photocatalytic degradation experiment of the composite coating was carried out with methyl orange as the model reactant. The experimental results show that the nano-TiO2 particles are uniformly distributed in the composite coating, and the microhardness of the composite coating is higher than that of the electroless nickel-phosphorus alloy in the plating state and after heat treatment, and the catalytic effect of the composite coating is comparable to that of the nano-titanium dioxide coating.
