Piston formed by powder metallurgical methods |
摘要 |
A piston includes a piston structure being unitarily formed in a powder metallurgy process, the piston structure having a crown assembly and a skirt assembly, at least a partial combustion chamber being formed intersecting a piston crown surface during the powder metallurgy process, the skirt assembly depending from the crown assembly and having two spaced apart pin bosses, each pin boss having a pin bore defined therein, a pair of opposed semi-circular skirt members, each skirt member extending outwardly from and being integrally joined to both of the pin bosses. The piston may be formed by executing a powder metallurgy process on at least two different metallic constituents to define a non-homogenous piston structure. A method of forming a piston is further included. |
