摘要	A scanning microelectrode was used to measure (he potential and current distributions on the metal surface of a brass-16Mn steel galvanic couple that was corroded in aqueous NaCl solutions with various concentrations. The potential and current distributions varied with the solution concentration and were also dependent on the distance from the brass-16Mn steel couple joint. These distributions were more symmetrical when the concentration of the solution was higher. The potential polarized greatly and the current density was larger near the couple joint. The potential and current distribution results were confirmed by surface observations of the corroded sample after the immersion test. Experimental results showed that corrosion was concentrated around the joint when solution concentration was low and was distributed more symmetrically as the solution concentration increased.
