Abstract
PURPOSE:To facilitate manufacture by forming the bevelled part of a valve from the composite strengthened metal consisting of short fibers, etc. as strengthened material and forming a shaft part from the composite strengthened metal consisting of alumina particles as strengthed material and arranging the strengthened material consisting of the particles so that the volume ratio gradually reduces from the shalt part to the bevelled part. CONSTITUTION:In a suction valve 10 consisting of a bevelled part 12 and a shaft part 14 continuous to the bevelled part 12, the bevelled part 12 is made of the composite strengthened metal which consists of the silicon carbide whiskers as strengthened material and aluminium alloy as matrix metal. While, the shaft part 14 is made or the composite strengthened metal which consists of the alumina particles as strengthened material and aluminium. alloy as matrix metal. In the bevelled part 12, in the boundary surface 12a between the bevelled part 12 and the shaft part 14, alumina particles exist in the nearly equal volume ratio to that in the shaft part 14, while on the bottom surface side 12b, the alumina particles exist in the least volume ratio and the volume ratio is gradually reduced from the boundary surface 12a to the bottom surface 12b.
