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 sphybrid bond content of from greater than or equal to about 60% to less than or equal to about 100%, and a carbon-carbon sphybrid 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.
