Pulse-plating of metals and alloys is of practical interest because the composition and physical properties of deposits can be controlled by a suitable choice of parameters.Despite the large number of studies devoted to pulse plating,very few concern Ni-Mo alloys.These have principally focused on the effect of pulse parameters on composition,internal stress and protective properties of Ni-Mo deposits.Recently,models for the prediction of the composition of pulse-plated Cu-Ni alloys have been developed [5-6].These take into account the influence of a displacement reaction occurring during the off-time when the less noble alloy component may corrode by reaction with the ions of the more noble component.Electrodeposition of Ni-Mo alloys from a citrate was studied with the aim to investigate whether such a displacement reaction takes place during the off-time.The results are then compared with models in the literature.
