发明名称 ENGINE PISTON AND A PROCESS FOR MAKING AN ENGINE PISTON
摘要 A piston for an internal combustion engine may include a substantially circular body composed of an aluminum containing base material defining a top portion having at least one cavity. At least one coating layer may be disposed on at least one area defined by at least one of the top portion and the at least one cavity. The at least one coating layer may include at least one chemical compound derived from a chemical reaction between the base material of the body and the at least one coating layer in response to friction generated by a dragging movement of a non-consumable rotary pin with the at least one coating layer.

主权项 1. A piston for an internal combustion engine, comprising: a substantially circular body composed of an aluminum containing base material defining a top portion having at least one cavity, and at least one coating layer disposed on at least one area defined by at least one of the top portion and the at least one cavity wherein the at least one coating layer includes at least one chemical compound derived from a chemical reaction between the base material of the body and the at least one coating layer in response to friction generated by a dragging movement of a non-consumable rotary pin with the at least one coating layer.
