Patent number: 11047062Abstract: [Technical Problem] An object is to provide a heat insulation coat having a novel form/structure different from conventional ones. [Solution to Problem] The present invention provides a heat insulation coat having a spongy body that is composed of non-linear pores and a skeleton incorporating the pores. The skeleton is an amorphous body comprising Al, Si, O, and impurities and has an amorphous peak specified by X-ray diffraction analysis at a position of 3.5 ? or more as the lattice spacing. The heat insulation coat has an apparent density of 1 g/cm3 or less, a volumetric specific heat of 1,000 kJ/m3·K or less, and a thermal conductivity of 2 W/m·K or less. The spongy body is obtained through forming a base layer, such as by thermal-spraying an aluminum alloy that contains a large amount of Si, and performing an anodizing process by AC/DC superimposition energization on the base layer. The amount of Si in the base layer may be, for example, 16 to 48 mass % with respect to the alloy as a whole.Type: GrantFiled: February 26, 2020Date of Patent: June 29, 2021Assignee: Toyota Jidosha Kabushiki KaishaInventors: Toshio Horie, Fumio Shimizu, Kenji Fukui, Naoki Nishikawa
