Abstract

A component for an engine is provided. The component includes a thermal barrier coating applied to a body portion formed of metal, such as steel or another ferrous or iron-based material. According to one embodiment, a bond layer of a metal is applied to the body portion, followed by a mixed layer of metal and ceramic with a gradient structure, and then optionally a top layer of metal. The thermal barrier coating can also include a ceramic layer between the mixed layer and top layer, or as the outermost layer. The ceramic includes at least one of ceria, ceria stabilized zirconia, yttria, yttria stabilized zirconia, calcia stabilized zirconia, magnesia stabilized zirconia, and zirconia stabilized by another oxide. The thermal barrier coating can be applied by thermal spray. The thermal barrier coating preferably has a thickness less than 200 microns and a surface roughness Ra of not greater than 3 microns.
