ABSTRACT:
In support of advanced solar central receiver programs, six commercially available, iron-based construction materials were exposed to molten NaN02- NaN03-KN03 salt at 823K for periods up to 6 months. After 1 month of exposure, oxide coatings had formed on each alloy; the amount of

oxidation ranged from 10 mg/cm2 for low carbon steel to ~ 0.1 mg/cm2 for 310 stainless steel. Analysis of the oxide surface of a 5% chrome alloy indicated a chromia enriched layer was present at the oxide/metal interface. An iron oxide rich layer was present at the outer oxide surface which contacted the molten salt. Show Less
