【Abstract】 A Study was made on the surface potential of LY12-CZ Al-alloy specimens with zincified 30CrMnSiA steel fasteners in 3. 5 × 10-4 NaCl solution using the technique of micro-electrode potential measuring. The results proved that the distribution of surface potential field around the interference fit hole was mainly affected by galvan-ic coupling and the amount of interfence fit affected galvanic couping corrosion.更多还原
