Piston and Method of Piston Remanufacturing

摘要

A method of remanufacturing a piston includes machining an exterior surface of a body of the piston to define a reference surface. The reference surface is inwardly offset relative to a portion of the exterior surface adjacent the reference surface. The body is made from a body material comprising a metal. A layer of a cold spray powder is applied to the reference surface via cold spraying to define a piston blank surface. The piston blank surface is outwardly offset relative to the portion of the exterior surface adjacent the reference surface. The cold spray powder is made from a powder material comprising the metal. The piston blank surface is machined to define a piston finish surface. The piston finish surface has a dimension which is within a predetermined range.
