MANUFACTURING METHOD OF ENGINE COMPONENT
To provide a manufacturing method of an engine component with a porous ceramic layer which can suppress a deformation and a distortion of the engine component.SOLUTION: A manufacturing method of this disclosure includes a process for forming a paste layer at least at one portion of a surface of an engine component material by making paste containing a ceramic layer forming material and a pore forming material adhere to at least one portion of the surface of the engine component material, a process for forming a ceramic precursor layer by hardening the paste layer at a temperature lower than a melting point of the pore forming material, and a process for combusting or evaporating the pore forming material, and forming a porous ceramic layer by heating the ceramic precursor layer at a temperature equal to or lower than 350°C.SELECTED DRAWING: Figure 3
【課題】本開示は、エンジン部品の変形及び歪を抑制することができる、多孔質のセラミック層付きのエンジン部品の製造方法を提供する。【解決手段】本開示の製造方法は、エンジン部品材料の表面の少なくとも一部分にセラミック層形成材及び気孔形成材を含むペーストを付着させて、前記エンジン部品材料の表面の少なくとも一部分にペースト層を形成すること、前記ペースト層を、前記気孔形成材の融点よりも低い温度で硬化させて、セラミック前駆体層を形成すること、及び前記セラミック前駆体層を３５０℃以下の温度で加熱して、前記気孔形成材を燃焼又は蒸発させると共に多孔質セラミック層を形成すること、を含んでいる。【選択図】図３
