A hard coating for a substrate or portion of a razor blade wherein a main layer of the hard coating includes graphene and/or any combination of derivatives thereof. The graphene may be deposited on the substrate or portion of the razor blade using plasma assisted chemical vapor deposition (PECVD) or similar process.

Coated razor blades comprising graphene

A razor blade comprising a blade substrate with a blade edge substrate portion ending in blade tip. The razor blade is covered by a strengthening coating deposited on the blade edge substrate portion via a deposition process. The deposition process causes a hardness value of the strengthening coating layer to be increased, which, among other factors, allows for a decreased thickness of the blade substrate with coating. The blade substrate with coating has (i) a thickness of between about 1.57 and 2.37 micrometers measured at a distance of about five micrometers from the coating tip, (ii) a thickness of between about 4.62 and 6.74 micrometers measured at a distance of about twenty micrometers from the coating tip, and (iii) a thickness of between about 19.82 and 27.52 micrometers measured at a distance of about one hundred micrometers from the coating tip.
