冷却水中SO_4^(2-)对凝汽器不锈钢管的缓蚀作用

Corrosion-resistant Effect of SO_4^(2-) in Cooling Water on Stainless Steel Tubes of Condenser

用电化学方法进行了大量试验，认为C1-对不锈钢管是侵蚀性离子，SO42-对不锈钢管是缓蚀性离子，在选用不锈钢管材时要综合考虑冷却水中C1-和SO42-对不锈钢管的缓蚀作用．

The technical and economical property of stainless steel tubes is good for application in condensers and the prospect is bright in China, but the Corrosion-resistant properties are quite different among stainless steel tubes. The material selection should be in accordance with water condition, especially in accordance with the different effects of C1- and SO42- Many tests with electrochemical methods show the result.
