Chemical compatibility of F82H and 316L in liquid metal heat transfer mediums Li, Na and NaK

Atomic spectrometry update: review of advances in the analysis of metals, chemicals and materials

“…Lithium, sodium and NaK liquid metals are candidate heat transfer mediums installed in the irradiation capsule of advanced fusion neutron sources. 171 In this work, Hosaka et al undertook corrosion tests at temperatures of up to 823 K to assess compatibility of these liquid metal materials with the steel materials F82H and 316L . The technique of TOF-SIMS was used to discover that the liquid Li caused depletion of C, Cr and Fe from steel, and Na and K corrosion occurred because of Na diffusion into the steel matrix and through surface oxidation.…”
