Description

Supercritical water oxidation (SCWO) holds a great potential to destroy organic waste. One of the major challenges in this process is to control the corrosion and SCC of structural materials by severe corrosive environment. However compared to the study of chemical processes in supercritical environment, there are only a few studies regarding corrosion and SCC. The cracking of an autoclave made of Hastelloy C-276 has been analyzed in this study. The autoclave was used to study the corrosion mechanism of SUS316 in sodium chloride solutions under supercritical and subcritical conditions. The results revealed the importance of the environment inside the cracks for crack growth. The probable mechanism for cracking in this supercritical application has been proposed.
