摘要： Concave part is formed in a crown surface of the top of piston made of an aluminum alloy. This concave part is filled with mixed powder constituted of zirconia powder as a filler material and pure aluminum powder as a bonding material. Solid cylindrical rotary implement is brought into contact with concave part filled with mixed powder, and then pressed against piston under load while being rotated. Mixed powder is softened by frictional heat with rotary implement, whereby mixed powder is bound in a solid phase to concave part to form low thermal conductive part. With this, the bonding strength of low thermal conductive part to the crown surface of the top of the piston is improved.

摘要： The present invention provides piston production device and piston production method capable of surely holding friction-resistant ring regardless of presence or absence of decrease in accuracy of outside diameter of holding pin. Device has lower mold provided thereinside with cavity for forming piston and having opening, upper mold provided movably to open/close opening of cavity, and three holding pins rotatably supported by holding holes of upper mold and having top end portions protruding from lower surface of upper mold. Top end portions have flat holding surfaces formed by cutting tip end sides of top end portions in half from tip end edges along axial direction and stepped surfaces formed from upper ends of holding surfaces toward radial direction. By rotating holding pins in synchronization with each other in the same direction, friction-resistant ring is held by three points of holding surfaces.
