In order to achieve higher operating temperatures in fossil energy systems, where sulfur and water vapor can cause severe oxidation problems, the corrosion resistance of Fe- and Ni-base alloys must be improved. In power generation applications, typical examples of surface damage include: (1) accelerated high-temperature fire-side corrosion associated with the presence of molten alkali-containing salts; (2) accelerated medium-temperature fire-side corrosion associated with the presence of a low oxygen activity environment and sulfur; and (3) steam-side oxidation of tubing, piping and valves in fossil fuel-fired boilers. Grant applications are sought to develop protective coatings and coating techniques for the Fe- and Ni-based alloys, and for nickel-based superalloys as well. The coatings must provide superior corrosion resistance in oxidizing, sulfidizing, carburizing, and water-containing environments, should show adhesion on the substrate (the tube outsides), as well as slide- and anti-stick-properties on the surface at the same time. Nano-technology approaches are encouraged. The protective coatings and coating techniques should be optimally designed as part of the overall power generation system, should be maintainable, and should be capable of non-intrusive evaluation to determine remaining life. To this end, model coatings should be fabricated for corrosion testing and diffusion studies in order to develop a comprehensive lifetime evaluation approach for the coatings. At least one ferritic and one austenitic alloy should be selected as substrate materials for study. The approach should provide sufficient data regarding lifetime performance in applicable environments.
