Research Progress of Alloy Corrosion in Supercritical Water Oxidation Condition
摘 要
超临界水氧化(SCWO)技术是近年发展起来的处理有机难溶废物的安全、经济、高效的新兴技术.本文简单阐述了SCWO反应的工作原理和流程,介绍了几种合金在SCWO环境下腐蚀性能的研究情况,通过比较可以看出经过晶界工程处理的镍基合金在SCWO环境下有较好的抗腐蚀性能.同时为我国在抗腐蚀合金研究方面的工作给出了建议.

Abstract
Supercritical water oxidation (SCWO) is a new technology which can safely,economically and effectively destroy various organic wastes.The operational principle and process of SCWO are described,corrosion of several alloys in SCWO condition is introduced.It is showed that the corrosion resistance of nickel alloy treated with grain boundary engineering is better than other alloys.
