Abstract | To provide a heat insulation film that does not peel and the like even if formed on a top surface of a piston and used in a severe environment such as the inside of a combustion chamber of an engine, and a vehicular heat insulation component provided with the heat insulation film.SOLUTION: A vehicular heat insulation component in the present invention is given a heat insulation property by forming a heat insulation film 1 on at least a part of a surface of a heat insulation target component 2 such as a piston of an engine. The heat insulation film 1 includes at least an inorganic compound layer 10 with a Vickers hardness (HV) of 50 to 100, in which one or more kinds of scaly inorganic particles 12 selected from a group of mica, talc, and wollastonite are scattered in an inorganic compound 11 formed from alkoxide. The inorganic compound layer 10 is baked by emitting light with a wavelength of 500 nm or less, thereby improving the hardness of the inorganic compound layer 10 to the aforementioned HV50-100 while suppressing a temperature rise of the heat insulation target component 2.SELECTED DRAWING: Figure 1
【課題】ピストンの頂面に形成されてエンジンの燃焼室の内部等の過酷な環境で使用される場合であっても剥離等することのない遮熱膜及び該遮熱膜が形成された車両用遮熱部品を提供する。【解決手段】本発明の車両用遮熱部品は,エンジンのピストンなどの遮熱対象部品2の表面の少なくとも一部に遮熱膜1を形成して遮熱性を付与したもので,この遮熱膜1は,アルコキシドから形成された無機化合物11中に,マイカ,タルク,及びウォラストナイトの群より選択された1又は複数種類の鱗片状の無機粒子12が分散された,ビッカース硬度(HV)で50~100の硬度を有する無機化合物層10を少なくとも含む。無機化合物層10を500nm以下の波長の光の照射によって焼成することで,遮熱対象部品2の温度上昇を抑制しつつ,無機化合物層10の硬度を前掲のHV50~100に高めることができる。【選択図】図1 |
