A used component, such as an engine block or engine head, has at least one dimension that does not match a dimensional specification for the component. A thermal spray coating of FeAlSiC is applied to build up the dimension. The excess coating is milled off so that the body and coating have a second shape that matches the dimensional specification for the component. The coating has an ordered DO3 crystal structure with a stable aluminum oxide scale that produces oxidation resistance at about 700° C.
