CeOx Coating Presentation

In order to produce power more efficiently and cleanly, the next generation of power plant boilers, turbines, solid oxide fuel cells (SOFCs) and other essential equipment will have to be operated at extreme pressures and temperatures, in what is known as the "ultrasupercritical" range. This range involves pressures up to 5,400 psi and temperatures up to 1,400°F. Even nickel-based superalloys and stainless steels suffer from excessive oxidation at these conditions, leading to the premature failure of components. A possible solution is to coat the metallic components with a protective layer of a ceramic oxide such as cerium oxide, then thermally treat the alloy so that Ce diffuses into the surface of the bulk metal alloy.
