摘要

研究了钯电镀液的一些性能。结果表明，提高电流密度可降低钯的电流效率，提高钯的沉积速度，表明镀液的搅拌是提高电流效率的有效途径。柠檬酸钾和草酸铵溶液浓度的选择主要取决于柠檬酸钾对钯离子的络合能力和草酸铵的溶解度。实验结果表明，该电解液具有良好的抛射力和良好的遮盖力。

Study on some properties of the electrolyte solution in the electrodeposition of palladium

Some properties of Pd electroplating solution were studied. The results showed that current efficiency and velocity of palladium deposition were decreased and increased respectively by raising the current density, which indicated that the stirring of plating solution was an effective route to raise current efficiency. The choice of concentrations of potassium citrate and ammonium oxalate in solution was mainly determined by the complexing ability of potassium citrate for the palladium ion and the solubility of ammonium oxalate. The electrolyte was shown to have a good throwing power and excellent covering power Hull cell tests showed that an adherent, smooth, bright and white Pd electrodeposit could be obtained.

期刊介绍： Transactions of the Institute of Metal Finishing provides international peer-reviewed coverage of all aspects of surface finishing and surface engineering, from fundamental research to in-service applications. The coverage is principally concerned with the application of surface engineering and coating technologies to enhance the properties of engineering components and assemblies. These techniques include electroplating and electroless plating and their pre- and post-treatments, thus embracing all cleaning pickling and chemical conversion processes, and also complementary processes such as anodising. Increasingly, other processes are becoming important particularly regarding surface profile, texture, opacity, contact integrity, etc.
