电镀镍磷合金老化镀液资源化利用的研究


Spent electroplating bath is dangerous discard liquor,because it contains heavy metal.A new means to treat the spent electroplating bath of nickel-phosphorus alloy is developed in this paper.This means can transform the spent electroplating bath into the usable electroless plating solution.The effect of nickel ion concentration of the transformed solution on the deposition rate and the stability of the transformed solution are discussed.The results show that the nickel ion concentration affects the deposition rate and stability clear-ly.Based on the above conclusion,the optimized proportion of the transformed solution is established.The binding force of coatings are tested;the micro-hardness of coatings at different test points of cross section are tested,and the micrograph of coatings surface and cross section are observed.The results reveal that the coat-ing is of eligible adhesion and medium hardness,compact and smooth,with the content of phosphorus in coating stable.
