摘要
介绍上海电力学院电化学研究室(亦即国家电力公司热力设备腐蚀与防护重点实验室)采用电化学方法和浸泡试验对多种HSn70-1B和HSn70-1A管样的测试。结果表明,在模拟冷却水中,浸渍初期多数HSn70-1B试样的耐脱锌腐蚀能力优于HSn70-1A,使其耐蚀性略优于HSn70-1A。
The corrosion resistance of some HSn70-1A and HSn70-1B brass tubes in simulated cooling water has beeninvestigated by electrochemical measurement methods and immersion tests. It is shown that the HSn70-1B samples havea larger dezincification resistance than HSn70-1A ones at the initial immersion stage, resulting in a little better corrosionresistance for HSn70-1B.
