Abstract

Ferritic stainless steels are being considered as potential interconnect materials for solid oxide fuel cells (SOFCs), in part because of their low cost relative to alternatives. These materials are, however, susceptible to degradation over time. In this study Co has been deposited on substrate AISI 430 Ferritic stainless steel by pack cementation process. In order to optimize the quality of the formed coating, The effective factors of pack cementation process was investigated by changing the factors, which are salt activator content in the pack powder (0.75-3%w.t.), deposition temperature (725-8000) and deposition time (1.5-3h). The as-coated samples were examined with Scanning Electron Microscopy (SEM). It was revealed that each parameter affects the coating thickness , coating quality and integrity.
