Effect of FeCl3 in NaCl-MgCl2 molten salts on the corrosion behavior of 316 stainless steel at 600 °C
Source abstract
Abstract
The effect of FeCl 3 addition on the corrosion of 316 stainless steel (316SS) in NaCl-MgCl 2 salts at 600 °C was studied through a static corrosion test. FeCl 3 added into NaCl-MgCl 2 salt reacted with Fe in 316SS and accelerated the corrosion of 316SS. After corrosion, Fe 2+ and Fe 3+ coexisted in the NaCl-MgCl 2 salt, and the concentration of Fe 2+ was higher than that of Fe 3+. With the increased FeCl 3 concentration in NaCl-MgCl 2 salt, the grain boundary corrosion of 316SS was aggravated, and the concentration difference of Fe 2+ and Fe 3+ in the salt increased after corrosion.
