This study evaluates the effect of donor-doped SrTiO3 (La0.2Sr0.8Ti0.9Ni0.1O3-delta, LSTN) coating on chromia growth on the surface of porous stainless steel (STS). During subsequent exposure to wet H-2 atmosphere at 800 degrees C, the porous STS oxidizes, and its Ohmic resistance increases slowly for 300 h to an area-specific resistance (ASR) similar to 2.5 m Omega cm(2), but at a much slower rate does uncoated STS and to a much lower ASR than that of uncoated STS (similar to 17.9 m Omega cm(2)). The estimated parabolic rate constant indicates that the porous LSTN-coated STS may be used at temperature <680 degrees C for similar to 10 y. (C) 2017 Elsevier B.V. All rights reserved.
