Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A razor blade, comprising: a substrate bearing a cutting edge; a hard coating disposed on the cutting edge, wherein the hard coating includes a main layer having a graphene or a graphene-based material; and an outer lubricious coating covering the hard coating that facilitates a reduction in friction between the razor blade and a skin surface of a user, wherein the graphene-based material is selected from the group consisting of graphite, graphite oxides, graphite nanoplatelets, carbon nanotubes (CNTs), graphene oxides, and any combinations thereof. 2. A shaving device, comprising one or more razor blades of claim 1 . 3. The shaving device of claim 2 , wherein the one or more razor blades include at least one or more strips of stainless steel having at least one cutting edge. 4. The razor blade of claim 1 , wherein the razor blade hard coating further comprises an interlayer below the main layer. 5. The razor blade of claim 1 , wherein the razor blade hard coating further comprises an overcoat layer above the main layer and below the outer lubricious coating.
