Abstract
The oxidation characteristics of ferritic stainless steel (Crofer22APU), a potential candidate for interconnects in solid oxide fuel cells, were studied. Carbon was introduced on the surface by ion implantation, and both the carbon-implanted and unimplanted samples were subjected to oxidation at 800°C for 500 h. Ion implantation produced a carbon-rich amorphous region at the top surface. Fast diffusion induced by ion implantation promoted the formation of spinel oxides. The carbon-implanted samples showed significantly less mass gain than the unimplanted samples.
