Abstract
Current density-time curves were measured at various cathodic potentiostatic pulses of short duration (⩽ 0·1 s) on stationary and moving horizontal copper wires of 0·51 mm diameter in 0·24 M CuSO4-2·36 M H2SO4 solution. The magnitudes and the shapes of theI-t curves were greatly influenced by the wire speeds. The limiting current densities from these transients,EIL, are higher and increase with wire speed at a smaller rate than the potentiodynamicIL. The role of uncompensated IR-drop is discussed.
