The effect of temperature in the range from 350 to 650°С on the morphology of brass grade L63 (37 wt % Zn) was studied during selective anodic dissolution in the eutectic salt melt of lithium, cesium and potassium chlorides. Anodic polarization is accompanied by a change in the state of the surface of the electrodes in connection with the release into the corrosive medium of the electronegative component of the alloy-zinc, as well as the vacancy-induced rearrangement of the electropositive component, copper. The methods of invesE tigation used in this work: microscopy, gravimetry, chemical analysis, and hydrostatic weighing-allowed us to evaluate the patterns of formation of a developed anodic surface under the galvanostatic regime of electrochemical dissolution of a bimetallic alloy. The increase in temperature led to a decrease in the selectivity of dissolution of the alloy, porosity and develE opment of the surface of the resulting materials.
