Electrochemical determination of porosity in nickel electroplates on a uranium alloy

This study has shown that for U-Ti alloy specimens galvanically coupled to a nickel sheet in KCl electrolytes, the corrosion potential varies linearly with the logarithm of the exposed area fraction of uranium alloy. It was possible to calibrate the technique so that the exposed base metal area fractions of uranium alloy specimens plated with nickel could be estimated to a reasonable approximation. This technique is relatively nondestructive and offers the advantages of simplicity and high sensitivity, particularly at low porosities. (U.S.)
