“…The aims of this study are to determine the effect of alloy purity as well as Mn and Ti contents on the oxidation behavior and the scale area specific resistance (ASR) of the Fe-22Cr alloys, and to compare the performance of these alloys with commercial ferritic alloys such as Crofer22 APU and Ebrite. In addition, a Ni-based alloy Haynes 242 is included in the evaluation, which exhibits a relatively low coefficient of thermal expansion (CTE) and a potential to form an NiO outer layer atop a chromia inner layer upon thermal exposure [28]. The potential of these alloys as intermediatetemperature SOFC interconnects will be discussed based on the experimental results.…”

“…En la literatura, se ha resumido el estricto contenido de Cr 13 , el cual varía aproximadamente entre 20-25 % para asegurar la formación de una continua capa protectora de Cr 2 O 3 . Se debe tomar en cuenta que un bajo contenido de Cr (5-10 %) utilizado como interconector, reduce significativamente la resistencia a la oxidación 15,16 . Los aceros de Cr bajo (<5 %), se componen prácticamente de óxido de Fe acompañado de precipitados tipo Cr 2 O 3 y/o espinelas de FeCr 2 O 4 .…”
