The effect of temperature in the range from 350 to 650°С on the morphology of L63 brass (37 wt % Zn) during selective anodic dissolution in the eutectic salt melt of lithium, cesium and potassium chlorides is studied. Anodic polarization is accompanied by a change in the state of electrode surface due to the passage of the electronegative alloy component (zinc) into a corrosive medium and to the vacancy-induced rearrangement of the electropositive component (copper). Microscopy, gravimetry, chemical analysis, and hydrostatic weighing are used to estimate the laws of formation of a developed anode surface under galvanostatic conditions of the electrochemical dissolution of the bimetallic alloy. An increase in the temperature leads to a decrease in the selectivity of alloy dissolution, the porosity, and the developed surface of the materials.
