ABSTRACT:
A powertrain component (10) for use in an internal combustion engine, the powertrain component comprising a coating system including an amorphous or nanocrystalline ceramic film (30). The powertrain component (10) also includes an interlayer (42) formed between the film and the component. The interlayer (42) accommodates stresses engendered by formation of the film (30), and thereby improves adherence of the film (30) to the substrate (10). To enable engineering of desired surface properties, the film (30), the interlayer (42), or both may be provided with a graded composition profile.
