INTERNAL HEAT-RESISTANT COATINGS FOR ENGINE COMPONENTS
PROBLEM TO BE SOLVED: To provide internal heat-resistant coatings for engine components.SOLUTION: A hot gas path component for an engine may generally include a substrate extending between an outer surface and an inner surface opposite the outer surface. The outer surface may be configured to be exposed to a hot gas path of the engine. In addition, the substrate may be formed from a non-metallic composite material. The hot gas path component may also include a heat-resistant coating disposed on the inner surface of the substrate. The heat-resistant coating may be applied to the inner surface so as to have a non-uniform distribution along at least a portion of the inner surface, where the non-uniform distribution provides for change in a thermal gradient experienced across the hot gas path component between the outer and inner surfaces of the substrate.SELECTED DRAWING: Figure 1
【課題】エンジン部品用の内部耐熱皮膜を提供する。【解決手段】エンジン用の高温ガス経路部品が、一般に、外面と外面の反対側の内面との間に及ぶ基材を備えることができる。外面を、エンジンの高温ガス経路に曝されるように構成することができる。更に、基材を、非金属複合材料から形成することができる。高温ガス経路部品は、基材の内面に設けられた耐熱皮膜を更に備えることができる。耐熱皮膜を、内面の少なくとも一部分に沿って不均一な分布を有するように内面に施工することができ、不均一な分布は、基材の外面と内面の間の高温ガス経路部品で経験される熱勾配の変化に対処する。【選択図】図１
