抽象的。 (Co,Mn)3O4 尖晶石前驱体层的电沉积已成为制备固体氧化物燃料电池 (SOFC) 金属互连涂层的新方法。 (Co,Mn)3O4尖晶石薄膜可以通过电沉积Co-Mn合金层的氧化热处理获得。本文研究了喷砂不锈钢基体对 Co-Mn 合金电沉积的影响。喷砂增加了Co-Mn合金中Co的含量,缩短了成核的起始时间,并导致表面纳米化。此外,对基材进行喷砂可以防止金属氢氧化物中间层的形成,加速相互扩散,并提高(Co,Mn)3O4尖晶石涂层的附着力。
Abstract. The electrodeposition of (Co,Mn)3O4 spinel precursor layers has emerged as a new method to prepare metallic interconnect coatings for solid oxide fuel cells (SOFCs). (Co,Mn)3O4 spinel films can be obtained via the oxidative heat treatment of an electrodeposited Co-Mn alloy layer. Herein, the effects of sandblasting stainless-steel substrates on the electrodeposition of the Co-Mn alloy were investigated. Sandblasting increased Co content in Co-Mn alloy, decreased the onset time of nucleation, and lead to surface nanocrystallization. Furthermore, sandblasting the substrate prevented the formation of the metal hydroxide interlayer, accelerated interdiffusion, and improved the adhesion of the (Co,Mn)3O4 spinel coatings.
