Piston for internal combustion engine and material therefore |
摘要 |
A method of forming a piston for a reciprocating machine such as an engine. The piston is formed from a powdered material that is comprised of aluminum alloyed with a material selected from the group of silicon (Si) and iron (Fe) having a particle diameter not greater than 10 mu m. The resulting alloy is then forged into a piston having a piston head and a piston skirt. The powder which is solidified and forged is formed by a process comprising the steps of forming an ingot from an alloy comprised of aluminum and an alloying material. This ingot is then melted and dispersed as a liquid in a chilling stream to form powdered metal particles. These powdered metal particles are then compressed into a blank having a cylindrical configuration for subsequent forging.
