摘要:
摘要： Two metallic alloys, containing comparable amounts of Cr, underwent oxidation in hot air simulating (the solid oxide fuel cell cathode atmosphere) for various periods. The results demonstrated that the oxidation kinetics of Crofer22 APU and equivalent ZMG232 followed the parabolic rate law and oxidation rates increased with temperature. Typical oxidation rates of Crofer22 APU and ZMG232 upon annealing treatment are approximately 0·21 orders of magnitude lower than that of ZMG232. An oxide scale electron probe microanalyser, a scanning electron microscope and X-ray diffractometer were adopted to verify the applicability of Fe-Cr based alloys in the solid oxide fuel cell interconnect component. Two alloys contain comparable amount of Cr, Mn and Fe, and their surface oxides as analysed are indicated to be Cr 2 O 3 and (Mn,Fe)Cr 2 O 4 spinel compound. In summary, Crofer22 APU had the best oxidation resistance of any of the alloys of interest. 出版者： London, England: Taylor & Francis 出版日期： 2012-02-01 出處： Corrosion engineering, science, and technology, 2012-02, Vol.47 (1), p.25-30 資源來源： Academic Search Premier (Ebsco) 版權： 2012 Institute of Materials, Minerals and Mining Published by Maney on behalf of the Institute 2012 版權： 2012 Institute of Materials, Minerals and Mining Published by Maney on behalf of the Institute 版權： 2015 INIST-CNRS 版權： Copyright Maney Publishing Feb 2012 識別號： ISSN: 1478-422X 識別號： EISSN: 1743-2782 識別號： DOI: 10.1179/147842211X13086631140539 識別號： CODEN: BRCJA3
