S2O2-3对Ni基合金671在NaCl水溶液中的点蚀行为的影响
, PP. 229-232
Keywords: Ni基671,超临界水,氧化
Abstract:
采用电化学测试方法对一种新兴的超临界水氧化(SCWO)废物处理技术设备用材——Ni基合金671在含S2O2-3根离子的NaCl水溶液中的点蚀行为进行了研究.结果表明，在纯Na2S2O3水溶液中，671合金不发生点蚀；而在纯NaCl水溶液中，671合金存在发生点蚀的氯离子临界浓度，且其耐蚀性优于Ni基合金690；在向NaCl溶液中添加不同浓度的S2O2-3根离子时，随添加S2O2-3浓度的逐渐提高，671合金的点蚀逐渐受到抑制，耐蚀性能提高，该特性将使得671合金在用于SCWO反应的设备制造材料方面极具优势.
