... of some alloys. Carbides are known to be resistant to attack by molten fluorides and could potentially be used to form a diffusion barrier on alloy surfaces. Alloy S31603 and alumina forming austenitic stainless steel OC5 were pre-oxidized in air or steam atmosphere to form surface oxide film. Chromium...

... Abstract The aim of this research focused on obtaining an understanding of the role of chromium in a binary iron aluminides in aqueous environments, i.e. 0.25 M sulfuric acid. Using a binary Fe-26Al and X8 CrNiS 18-9 alloy for comparison purposes, electrochemical potentiodynamic polarization...

... and higher cost alloy compared to UNS J92205. The lower and higher cost chemistries were determined based on cost and the corrosion resistance effects of nitrogen, chromium, nickel, and molybdenum. Ferric chloride corrosion tests (modified ASTM G48 standard) were used to determine the CPT of the three...
