Uranium surface electrochemistry and nickel electroplating interim report
Declassified 19 Feb 1971. An electrochemical technique, measuring the uranium potential to characterize the uranium surface resulting from a given surface preparation before the electrodeposition of nickel. This technique has enabled the investigation of such variables as exposure time, solution temperature, and H/sub 3/PO/sub 4/- concentration in the pickling step following an H/sub 3/PO/sub 4/-HCl anodic etch. It has also enabled evaluation of other pretreatments in terms of the active or passive condition of the uranium surface. Various plating baths and uranium surface preparations were evaluated through examination of the gas pitting, adherence, and porosity of nickel-plated uranium specimens. These plating results were correlated with the potential measurements to further substantiate the validity of using these measurements in the NaClO/sub 4/ solution to determine the suitability of a uraniuna surface for an adherent nickel electroplate.
