Abstract

PURPOSE:To improve abrasion resistance by forming a poppet type valve body part from the composite strengthened metal consisting of ceramic short fibers. etc., as strengthened material and forming a valve face surface from the composite strengthened metal consisting of the steel powder which is applied with soft nitriding treatment as strengthened material. CONSTITUTION:In a suction valve 10 consisting of a bevelled part 12 and a shaft part 14 continuous to the bevelled part 12, the shaft part 14 and the bevelled part 12 except a valve face part 16 arranged on the outer periphery of the bevelled part 12 are made of the composite strengthened metal which consists of the silicon carbide whiskers as strengthened material and aluminium alloy as matrix metal. While, the valve face part 16 is made of the composite strengthened metal which consists of the molded body made of the steel powder of SCM44O (JIS) which is prepared from the soft nitriding treatment of the compound layer having an average diameter of about 40mum as strengthened material and aluminium alloy as matrix metal. The steel powder which is applied with the soft nitriding treatment is arranged uniformly with a volume ratio of 50%.
