Abstract

High-temperature oxidation and hot corrosion resistance of solid oxide fuel cell (SFOC) interconnections can be improved by creating a thin film on the surface. For this Mn can be deposited on the surface of interconnections by pack cementation process. In this study Mn has been deposited on substrate AISI 430 Ferritic stainless steel. In order to make the best characteristics of the formed coating, the effective factors of pack cementation process was investigated by altering these factors, which are salt activator content in the pack powder (0.5–7%w.t.), deposition temperature (700–800°C) and deposition time (3–4 h). The as-coated samples were examined under Scanning Electron Microscopy (SEM) associated with Energy Dispersive Spectroscopy (EDS). It was revealed that each parameter affects the coating thickness, coating quality and integrity.
