A Near‐Frictionless and Extremely Elastic Hydrogenated Amorphous Carbon Film with Self‐Assembled Dual Nanostructure

A highly crosslinking network combined with a fullerene-like structure is disclosed in a hydrogenated amorphous carbon film. The very soft carbon film exhibits super-low friction and excellent wear resistance even under a Hertzian contact pressure comparable to its hardness under vacuum, which is an extraordinary tribological behavior in the filed of solid lubrication films or coatings.
