摘要：Aqueous acid nickel chloride and alkaline nickel sulfate bath were studied for electroless nickel plating on acrylonitrile-butadiene-styrene (ABS) plastic. Before electroless nickel plating,specimens were etched,sensitized and activated. Effects of sodium hypophosphite and sodium citrate concentrations on the thickness of electroless nickel plating were discussed. Aqueous acid nickel chloride bath comprising,nickel chloride 10 g L -1,sodium hypophosphite 40 g L -1,sodium citrate 40 g L -1 at pH 5.5,temperature 85oC with density of 1 Be/ in thirty minutes yielded thickest coating. Under comparable conditions,acid nickel chloride bath gave thicker deposits than alkaline nickel sulfate bath..
