Fabrication of Ni-Co film for enhancing the high-temperature corrosion resistance of interconnects in solid oxide fuel cells (SOFCs)
ABSTRACT Low-cost Ni-Co alloy coating was performed by electroplating technique to improve the high-temperature corrosion resistance of stainless steel interconnects in solid oxide fuel cells (SOFCs). The effect of plating on the surface morphology, microstructure and composition of Ni-Co alloys was investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD) and atomic force microscopy (AFM). The Ni-Co coatings were fabricated at thickness of around two microns and compared at different Ni-Co molar ratios. Corrosion performance of Ni-Co coating was evaluated in a muffle furnace under ambient atmosphere at 800℃ for 110 h. Co2NiO4 spinel oxides and Cr2O3 were found on the Ni-Co coated samples after the oxidation test. Results indicated that steel substrate corrosion protection improved with a low parabolic rate constant of 20 times after Ni-Co alloy electrodeposition coating. A smooth coating layer containing Co2NiO4 oxide with fewer defects promoted high oxidation resistance of the steel samples.
期刊介绍：
Materials at High Temperatures welcomes contributions relating to high temperature applications in the energy generation, aerospace, chemical and process industries. The effects of high temperatures and extreme environments on the corrosion and oxidation, fatigue, creep, strength and wear of metallic alloys, ceramics, intermetallics, and refractory and composite materials relative to these industries are covered.
Papers on the modelling of behaviour and life prediction are also welcome, provided these are validated by experimental data and explicitly linked to actual or potential applications. Contributions addressing the needs of designers and engineers (e.g. standards and codes of practice) relative to the areas of interest of this journal also fall within the scope. The term ''high temperatures'' refers to the subsequent temperatures of application and not, for example, to those of processing itself.
Materials at High Temperatures publishes regular thematic issues on topics of current interest. Proposals for issues are welcomed; please contact one of the Editors with details.
