ELECTROCHEMICAL BEHAVIOR OF BRASS (CuZn 63:37) IN BINARY MIXTURES OF N,N-DIMETHYLFORMAMIDE AND WATER.

Abstract

The electrochemical behavior of brass has been studied in N, N-dimethylformamide (DMF) and water mixtures at 30 C using the potentiostatic polarization technique, weight loss method, and solution analysis. The effects of dissolved oxygen and stirring have also been studied. The dissolution of brass has been found to be cathodically controlled, with the metal being more anodically active in the region of the greater percentage of water. The weight loss and solution analysis reveal preferential dissolution of zinc in the initial stages, which decreases progressively with time.
