Corrosion of Metallic Materials in 3LiCl-2KCl and 3LiCl-2KCl-UCl₃

Abstract

The corrosion of various metallic materials was investigated in 3LiCl–2KCl and 3LiCl–2KCl–UCl3 (5 wt. % U) melts under inert atmosphere. Metallic tantalum and molybdenum, nickel-chromium-molybdenum alloys (VDM® Alloy C-4, Hastelloy® G-35®, and specially designed KhN62M alloy) were investigated. The corrosion tests run for 100 h, and the temperature was varied from 450 to 750°C. The corrosion rates were determined by gravimetric technique and chemical analysis of quenched melts.
