Abstract

The addition of Ni to Mn-Co films was prepared by electroplating process. Film behavior under corrosive environment was investigated by oxidation techniques. The samples were kept under stagnant air at 800 °C in heat treatment furnace at operating temperature of SOFC for 100 hours. The surface morphology and films compositions were then examined. Mn-Co films with nickel amount of 18.8 wt.-% exhibited the best oxidation resistance. Ni-doped Mn-Co films show high antioxidation behavior because of high film density and crack-free film. The film is composed of many small particles with close packing, and the average particle size is about 1 μm. Film thickness is around 11 μm with surface roughness of 82.97 nm and it has good coherence with substrates. Optimization of nickel amount also plays an important role in antioxidation performance.

Kurzfassung

Die Zugabe von Ni zu Mn-Co-Filmen wurde mittels Elektroplattierens ausgeführt. Das Verhalten der Filme in korrosiven Umgebungen wurde mittels Oxidationstechniken untersucht. Die Proben wurden hierzu statisch bei 800 °C in einem Ofen für 100 Stunden wärmebehandelt, was der Betriebstemperatur einer Brennstoffzelle entspricht. Anschließend wurden die Oberflächenmorphologie und die Filmzusammensetzung untersucht. Die Mn-Co-Filme mit einem Nickelzusatz von 18,8 gew.-% zeigten die beste Oxidationsresistenz. Die Mn-Co-Filme mit Nickelzugabe wiesen ein gutes Antioxidationsverhalten aufgrund ihrer hohen Dichte und Rissfreiheit auf. Der Film ist aus vielen kleinen Partikeln in enger Packung aufgebaut, wobei die mittlere Partikelgröße etwa 1 μm entsprach. Die Filmdicke betrug 11 μm mit einer Oberflächenrauheit von 82.97 nm und sie hatte eine gute Kohärenz mit den Substraten. Die Optimierung des Nickelanteils hat eine wichtige Bedeutung hinsichtlich des Antioxidationsverhaltens.
