摘　　要：用极化曲线法研究了 Cl-、SO42 -对 3 0 4、3 16L不锈钢电极腐蚀行为的影响 ,表明 Cl-是侵蚀性离子 ,SO42 -是缓蚀性离子 ,在凝汽器不锈钢管选材时要综合考虑冷却水中 Cl-和 SO42The effect of Cl - and SO 4 -2 on the behavior of electrolytic corrosion of 304 and 316L stainless steel is studied by means of polarized curve method and the test result showed that Cl - is corrosive ion while SO 4 -2 is corrosion inhibiting ion. During material choice of stainless steel tube for condenser, the influence of Cl - ion and SO 4 -2 ion in the cooling water on stainless steel tube should be comprehensively considered.
