多孔不锈钢基体上钯膜沉积的制备研究
|
摘要
分别采用化学镀法、电镀法以及两者相结合的方式在孔径为5μm的多孔不锈钢基体上进行了致密钯膜的制备。采用SEM、EDS、XRD等对多孔不锈钢表面钯膜进行了表征。结果表明:以0.1 g/L的PdCl_2盐酸溶液对完成前处理的多孔不锈钢进行化学镀预镀后,再使用钯含量为17 g/L钯氨溶液进行电镀可制备出成分纯净的钯膜,此时,钯膜表面形貌平整致密且均匀,无明显坑洞和裂缝,膜厚10～20μm。
The preparation of dense palladium film on the porous stainless steel substrate with pore size of 5 um was carried out by electroless plating, electroplating and the combination of the two methods, respectively. The palladium films on the surface of porous stainless steel were characterized by SEM, EDS and XRD. The results show that the pure palladium film can be preplated by 0.1 g/L PdCl_2 hydroch loric acid solution to the pre-treated porous stainless steel and then prepared by electroplating with palladium content of 17 g/L palladium ammonia solution. The surface morphology of the palladium film is flat, dense and uniform, no obvious pits and cracks. The thickness of the film is about 10-20 μm
