    Abstract: A heat-rejection coating is applied to a metallic component of a gas turbine engine, preferably made of a nickel-base superalloy. A component surface is preferably pre-treated, as by polishing the component surface, thereafter pre-oxidizing the component surface, and thereafter applying a ceramic barrier coating onto the component surface. A reflective-coating mixture is air sprayed onto the pre-treated component surface. The reflective-coating mixture includes a metallic pigment, such as platinum, gold, palladium, and alloys thereof, and a reflective-coating-mixture carrier. The component with the reflective-coating mixture sprayed thereon is fired.

    Abstract: A piston for a diesel internal combustion engine including a crown portion at least partially formed of steel and having a combustion surface with a combustion bowl formed therein is provided. The combustion bowl presents a combustion bowl rim area, and a coating including at least one of a noble metal and a refractory metal is applied to substantially only the combustion bowl rim area. The coating is preferably applied in the areas of the combustion bowl rim area that are in line with the sprays of diesel fuel when the piston is in a top dead center position during operation of the engine.
