Abstract: Embodiments of the present innovation relate to a cylinder bore coating system which simultaneously combines both friction and wear properties to enhance engine efficiency and operating life. The cylinder bore coating system includes a relatively thin top layer, such as diamond like carbon layer (DLC), disposed over a thicker, relatively hard and high modulus coating (i.e., an under coating). This combination of layers provides both low friction as well as low wear characteristics to the engine bore, relative to conventional engine bore coatings.
