Resumo: | ABSTRACT: T91 ferritic-martensitic steel was exposed to Li, Na and K molten carbonates at 650??C under dynamic conditions up to 1000 h. After testing, three descaling methods, two from the ISO8407 and one from the ISO17245 stan-dards were applied to remove the corrosion products and determine the corrosion rates. The two ISO8407 methods were more appropriate although the procedure required several steps to fully remove the corrosion products. The ISO17245 method led to a higher mass loss affecting probably the base material. Oxides identi-fication was performed by XRD following step by step layers removal. Li-, Na-, K-containing oxides and chro-mates/chromites were detected. |
