Abstract: A vehicle part or component includes a surface that is configured to contact a fuel containing ethanol. The surface has a layer of non-hydrogenated diamond like carbon (NH-DLC) material disposed on the surface. The layer of NH-DLC has a thickness of from greater than or equal to about 100 nm to less than or equal to about 100 μm. The NH-DLC material has a carbon content of greater than or equal to about 90 atomic % (at. %), a carbon-carbon sp3 hybrid bond content of from greater than or equal to about 60% to less than or equal to about 100%, and a carbon-carbon sp2 hybrid bond content of from greater than or equal to about 0 to less than or equal to about 40%. The NH-DLC material is substantially free of hydrogen atoms. Methods for manufacturing the vehicle part or component are also provided.

Abstract: An example of the coated tool disclosed herein includes a substrate, a metal layer established on the substrate, a continuous metal carbide layer established on the metal layer, and a smooth, continuous, terminated diamond like carbon (DLC) layer established on the metal carbide layer. The DLC layer is to prevent metal, from a workpiece upon which the tool is to act, from adhering to the tool.
