Abstract
An apparatus for a combustion cylinder of a reciprocating piston engine includes a combustion cylinder end face component including a first side configured to face the combustion cylinder and extending in a radial direction of the combustion cylinder and a pocket recessed into the first side and including a recessed pocket surface. The combustion cylinder end face component may be one of a piston and a cylinder head. A thermal barrier coating is inlaid in the pocket. The thermal barrier coating includes a ceramic-metallic layer directly coating the recessed pocket surface and a ceramic layer directly coating the ceramic-metallic layer and including an outer surface facing the combustion cylinder.
