), therefore, Bi ion concentration was fixed to 4 mmol/L. The electro- deposition and cathodic polarization measurement were conducted in above solutions. This electrolyte was adjusted to pH 0 by H2SO4... by observation at ca. -5 mV. As mentioned above, it is considered that Bi electro- deposition reaction starts from ca. -5 mV. In Cu alone solution, cathodic current started to flow from ca. 100 mV......
of four common-used complexing agents on EN deposition rate and the stability of solution pH values were examined,either with an acetic pH buffer agent or absent of them.It is indicated that the pH buffering effect of them is dominative when the EN solution is lack of the pH buffer.Under this situation,the EN deposition rate increases with the concentration of complexing agents increasing.The EN......

Effect of Cerium Sulfate on Acidic Electroless Nickel Deposition刘海萍,李宁,毕四富摘 要:The effect of cerium sulfate on bath stability, deposition rate, reaction... on the deposition rate depends on its concentration. Deposition rate increases with increasing cerium sulfate concentration, and reaches a maximum at 2 mg·L-1. At higher concentration, the deposition rate decreases......
