are submerged in an acidic electrolyte that is either flowing or stationary. Insoluble and low-electrical-resistant copper is used as the cathode electrode. When a pulse current is sent to the two electrodes... for corrosion resistance against synthetic seawater with respect to pulse time.

and current densities. Compared with direct current electrodeposition, the thicker coating and finer grains can be obtained at lower temperature and current density by pulse electrodeposition. The electrodepostion velocity is about 0.24 ?m/min, which is faster than that by direct current electrodeposition. In 1 mol/L H2SO4, 3.5% NaCl and 10% NaOH solution, corrosion potential of Cr pulse-deposited film......
