Abstract
A method of making a piston with enhanced thermal conductivity. In one embodiment, the method includes providing a piston with an oil gallery, the piston made of a material; and depositing a layer of a material in the oil gallery, the material having a higher thermal conductivity than a thermal conductivity of the piston material. Another aspect of the invention is a piston having enhanced thermal conductivity.
