Abstract:
A heat shield component includes a substrate, and a heat shield film arranged on the substrate. The heat shield film includes a first layer arranged on the substrate, including pores, and having a thermal conductivity of 0.3 W/(m·K) or less and a volumetric specific heat of 1200 kJ/(m3·K) or less, and a second layer arranged on the first layer to provide closed pores between the first layer and the second layer. The heat shield film has a surface roughness on a top surface which is 1.5 μm Ra or less. The heat shield component can achieve high heat-insulating properties and an improved effect of reducing the emission amount of hydrocarbon in an internal combustion engine, for example.
