A temperature-following layer may be applied to a surface of components within an internal combustion engine. The temperature-following layer follows the temperature swing of adjacent gases (for example, in a combustion chamber). The temperature-following layer may be applied directly to a substrate, or the temperature-following layer may be an outer layer of a multi-layer thermal barrier coating. The multi-layer thermal barrier coating may include, for example, an insulating layer, a sealing layer bonded to the insulating layer, and a porous temperature-following layer disposed on the sealing layer. The sealing layer is substantially non-permeable and configured to seal against the insulating layer.
