Transmission Line Modeling Applied to Hot Corrosion of Fe-40at.pctAl in Molten LiCl-KCl Academic Article

abstract

• 2015, The Minerals, Metals & Materials Society and ASM International. The effect of Cu and Li additions to the intermetallic alloy Fe-40at.pctAl on the corrosion performance in an LiCl-55wtpctKCl molten eutectic salt was studied by means of electrochemical impedance spectroscopy, transmission line modeling (TLM), and cathodic polarization. The tests were done at 723K, 773K, and 823K (450C, 500C, and 550C), for 60and 720minutes. The element additions could improve the corrosion resistance of Fe-40at.pctAl in molten LiClKCl, while TLM could characterize and quantify the interfacial processes in hot corrosion. The polarization curves helped to establish the possible cathodic reactions in the experimental conditions.
