Abstract
This invention relates to a novel application of hard, low friction aluminum magnesium boride (AlMgB14, also known as BAM) based ceramic coatings to surfaces of razor components and in particular to blade edges of razor blades. On razor blade edges, these coatings may elevate blade performance, while also simplifying the manufacturing process.
Claims11
A razor blade apparatus comprising a sharpened substrate having at least one layer of BAM material disposed thereon, wherein one or more overcoat layers comprised of a composite of BAM and a second component is disposed on top of the BAM layer, wherein one or more interlayers are disposed between the layer of BAM material and the sharpened substrate and wherein said one or more interlayers and said one or more overcoat layers comprise an adhesion layer.
