This paper describes materials exposed to high reducing species like H2. an approach for achieving low corrosion potentials on structural temperature water, even without the addition or presence of This approach employs highly insulating coatings, e.g. yttria stabilized zirconia (YSZ) on structural materials to greatly restrict O2 transport rate to the metal surface while simultaneously preventing the formation of a differential aeration crevice cell because of its highly insulating character. Initial experimental data on 304 stainless steel (SS) coated by air plasma spray show that the corrosion potential of YSZ coated 304 SS...
