摘要
采用微电极电位测量技术.研究了镀锌30CrMnSiA钢螺栓干涉配合连接LY12-CZ铝合金试片在3.5×10^(-4)%NaCl溶液中的表面电位分布.结果表明,决定表面电位的主要因素是电偶作用,干涉量对电偶作用有重大影响.
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.
