Corrosion is a complex phenomenon involving metallic alloys and the surrounding environment. The various forms of corrosion suffered by metallic materials in aqueous environments have been extensively studied and codified. In contrast, studies of corrosion at high temperatures involving gaseous environments, liquids like molten salts, and solid deposits are more limited. There is, however, continued need for studies in this area due to their impact on a broad range of industries including those in the aerospace, power generation, chemical process, and petrochemical refining sectors. Some examples of these corrosion phenomena are oxidation in air, corrosion in molten salts, accelerated corrosion under thin molten salt films (hot corrosion), etc. In this talk, I will present and discuss some of the current research in my group in high temperature corrosion of metals. I will also discuss examples from our work on surface modification for elevated temperature corrosion protection. As time permits, I will point out collaborative opportunities that could be of potential interest.
