Abstract

PURPOSE:To improve the heat insulating and resisting characteristics of a combustion chamber forming material for an internal combsution engine by coating the contact surface side of the material with high temperature gas with contact member formed of nickel or iron porous metal. CONSTITUTION:When the contact surface of a piston is coated, for example, with porous metal 7 of nickel or iron alloy or the like, the pore opening diameter of the metal 7 becomes about 0.1mm. In order to prevent the interior of the piston from being polluted through the pores, ceramic is sprayed only on the surface of the metal 7 to close the pores. Since penetrated layer 9 is formed on the contacting surfaces between a piston mother material 2 and the metal 7 thus formed, the adhering strength of both the material 2 and the metal 7 becomes large. Accordingly, it can thus obtain a piston having superior heat insulating and resisting characteristics strong against crack and separation.
