摘要
A method of forming an insulated composite piston head may include: creating a preformed aluminum or aluminum alloy foam core; suspending the preformed foam core in a piston head mold; forming a molded piston head and removing it from the mold; depositing an insulating material on at least one surface of the molded piston head; performing at least one machining operation on the molded piston head so it conforms to a predetermined specification for the insulated composite piston head; and optionally applying a lubricious piston coating to at least a portion of the outer surface of the insulated composite piston head.
