    • Abstract:
      Estudos vêm sendo desenvolvidos para melhorar a resistência à oxidação em temperaturas elevadas do aço inoxidável ferrítico, os quais têm sido propostos para fabricação de interconectores de células a combustível do tipo óxido sólido de temperatura intermediária (IT-SOFC). Dentre os revestimentos empregados, os revestimentos cerâmicos de óxidos do tipo espinélio têm sido os mais aplicados. Nesse contexto, no presente trabalho foram obtidos revestimentos à base de Mn e Co sobre aço inoxidável ferrítico (AISI430), utilizando a técnica de dip-coating. Os filmes obtidos foram caracterizados quanto à morfologia por MEV e quanto à composição elementar por EDS. Foi possível obter do revestimento à base de Mn e Co continuo e aderente sobre o substrato metálico. ; Studies have been developed to improve the oxidation resistance at elevated temperatures of ferritic stainless steel, which have been proposed for the fabrication of intermediate-temperature solid oxide fuel cell interconnectors (IT-SOFC). Among the coatings employed, ceramic coatings of spinel-type oxides have been the most applied. In this context, in the present work Mn and Co based coatings were obtained on ferritic stainlesssteel (AISI 430), using the dip-coating technique. The films obtained were characterized as to morphology by SEM and as to elemental composition by EDS. It was possible to obtain a continuous and adherent Mn and Co based coating over the metallic substrate.
