Corrosion behavior of porous chromium carbide in supercritical water

The corrosion behavior of highly porous chromium carbide (Cr3C2) prepared by a reactive sintering process was characterized at temperatures ranging from 375°C to 625°C in a supercritical water environment with a pressure of 25–30MPa. The test results show that porous chromium carbide is stable in SCW environments at temperatures under 425°C, above which disintegration occurred. The porous carbide was also tested under hydrothermal conditions of …
