DIAMOND-LIKE CARBON COATING (DLC) FOR INJECTION APPLICATIONS FOR ETHANOL-CONTAINING FUEL MIXTURES

摘要

A vehicle part or component includes a surface configured to contact an ethanol-containing fuel. 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 greater than or equal to about 100 nm or less than or equal to about 100 μm. The NH-DLC material has a carbon content of greater than or equal to about 90 at% (At.%), A carbon-carbon-sp hybrid bond content greater than or equal to about 60% or less than or equal to about 100 % and a carbon-carbon sp hybrid bond content of greater than or equal to about 0 or less than or equal to about 40%. The NH-DLC material is largely free of hydrogen atoms. Methods of manufacturing the vehicle part or component are also provided.
