利用电刷镀工艺在316L不锈钢上制备了结合力良好的钯膜.使用扫描电子显微镜、X射线能谱、X射线光电子能谱(XPS)、质量损失实验和电化学测试研究了膜层的性能.结果表明,电刷镀钯膜主要是由钯元素构成的；XPS分析表明,膜层中的钯为金属态.电刷镀钯后的不锈钢试样在沸腾的20％硫酸溶液和含0.005 mol/L溴离子的甲酸和乙酸混合溶液中均显示了非常好的耐蚀性能.镀钯试样的腐蚀速率比不锈钢试样的下降了2个数量级.

Palladium films with good adhesive strength were deposited on 316L stainless steel by brush plating.Scanning electronic microscopy,energy dispersive X-ray spectroscopy,X-ray photoelectron spectroscopy (XPS),mass loss tests and electrochemical methods were used to study the properties of the films.The brush plated palladium film mainly consisted of palladium.XPS analysis indicated that palladium was present in the films as metal state.The palladium plated stainless steel samples showed excellent corrosion resistance in boiling 20％ H2SO4 solution and boiling acetic/formic acids with 0.005 mol/L Br ions added.The corrosion rates of the palladium plated 316L stainless steel samples were about two orders of magnitude lower than those of the original 316L stainless steel samples.This method provides a possibility to prepare protective palladium films on stainless steel facilities with large areas in industrial sites.
