Abstract

In order to investigate the corrosion mechanism of waste salt thermochemical treatment and screen suitable metal materials for use in the reactor, several common alloy materials, including 316L, Inconel625, Incoloy825, C276 and TA2, were selected and subjected to a 20 h short - term corrosion tests at 800, 850 and 900 °C in 80% NaCl-20% Na₂SO₄mixed salt. Results showed that Inconel625 could be used in the waste salt thermochemical treatment device. The Inconel625 alloy was subjected to a 10 d corrosion test. The corrosion products were analyzed by X- ray diffraction (XRD), scanning electron microscopy (SEM) and energy spectrum analysis (EDS). The main corrosion products were found to be NiO and Cr₂O₃. It was determined that the corrosion behavior followed the corrosion mechanism " oxidation activation theory" and the " acid - base melting model".
