The effectiveness of ethanolamines in electroless nickel plating is studied. It is shown that triethanolamine can be used effectively in place of ammonia in citrate based alkaline electroless nickel baths. By suitably adjusting the sodium citrate concentration, it is possible to codeposit a higher percentage of phosphorus. The bath is suitable for the deposition of ternary alloys of nickel, e.g. Ni-Cu-P and Ni-Sn-P which show improved corrosion resistance. It is possible to get adherent and coherent electroless nickel on aluminum and its alloys.
