摘要
为了开发超临界水氧化技术和超临界水电力技术 ,研究了五种不锈钢和一种镍基合金在 192、2 92和392°C高温高压水中的耐腐蚀性。结果表明 :在试验条件下 ,所有的合金都表现出某种程度的不稳定性 ,均匀腐蚀轻微 ,点蚀是最主要的腐蚀形式。相比较而言 ,高合金不锈钢Sanicro2 8和镍基合金Ni82 5在该环境中表现出较好的耐蚀性。
Five types of stainless steels and one type of nickel base alloy were tested for corrosion resistance in high temperature high pressure water at 192, 292, and 392°C. The results show that all the alloys exhibited instability to some extents in the environments, especially at 292 and 392°C. Pit initiation was the most possible way of the corrosion while weight loss was almost negligible. In comparison, Sanicor28 (a type of high alloy stainless steel) and Ni825 (the nickel base alloy) showed the better corrosiion resistace in the testing conditions.
