Abstract: A method of extending the lifetime of an electroless nickel plating bath by avoiding the addition of unwanted anions to the process and of improving the pH stability of the bath and minimizing additions of pH correcting additives. The method includes the steps of (a) depositing electroless nickel from an electroless nickel plating bath onto a substrate, wherein the electroless nickel plating bath preferably contains a source of nickel ions and a source of hypophosphite ions; (2) immersing a nickel anode in the plating bath; (3) completing the circuit by utilizing a cathode separated from the nickel bath by an ion exchange membrane and using a catholyte comprising an acid or a salt thereof; and (4) passing a current through the bath. Nickel is dissolved into the plating bath to maintain the nickel concentration and hydrogen is discharged from the cathode.
Abstract translation: 通过避免向该方法添加不需要的阴离子并改善浴的pH稳定性并最小化添加pH校正添加剂来延长化学镀镍浴的寿命的方法。 该方法包括以下步骤：（a）从化学镀镍浴中将无电镀镍沉积到基底上，其中无电镀镍浴优选含有镍离子源和次磷酸根离子源; （2）将镍阳极浸入镀浴中; （3）利用离子交换膜从镍浴分离的阴极和使用包含酸或其盐的阴极电解液完成电路; 和（4）通过电流通过浴。 将镍溶解到电镀液中以维持镍的浓度，并且从阴极排出氢。

Abstract: The invention consists of a method for producing an adherent copper coating on a zinc or zinc alloy article without the use of cyanide as a component of the process. The zinc or zinc alloy article is first immersed in an aqueous nickel pyrophosphate solution and is then electroplated with a copper pyrophosphate solution. The method produces an adherent copper coating on the zinc or zinc alloy, which can be deformed without any loss of the copper coating.

Abstract: A method for enhancing the solderability of a metallic surface is disclosed where the metallic surface is plated with a silver plate prior to soldering, which immersion silver plate is treated with an additive comprising a mercapto substituted or thio substituted silane compound. Preferred post treatments comprise 3-mercapto propyl trimethoxysilane and/or 3-oxtanoylthio-1-propyltriethoxy silane.
