【摘要】 超声波与电沉积相结合制备Pd-Ni-P合金,通过SEM、EDX、XRD和Tafel曲线等方法分析了Pd-Ni-P镀层的形貌、成分、结构和耐腐蚀性。结果表明:超声波作用使沉积层中钯的含量增加,镀层表面更致密均匀,显著增强了镀层在1.0 mol·L^-1NaOH溶液的耐腐蚀性能。更多还原

【Abstract】 In the solution containing PdCl₂ 3.5 g/L,NiSO₄·6H₂O 10 g/L,H₃PO₃20g/L,H₃BO₃20g/L,ethylene diamine 4.6 g/L,pH 4.0,50℃,Pd-Ni-P alloy films were electrodeposited with ultrasound.The morphologies,composition,structures and corrosion resistance in a 1.0 mol(L^-1 NaOH solution of alloys were investigated with SEM,EDX,XRD and Tafel curves.The results indicated that,under ultrasonic condition,the morphologies became more compact and smoth,and the Pd content increased while Ni content decreased.Pd-Ni-P alloy obtained ultrasound showed the higher corrosion resistance.更多还原
