Abstract: A method of manufacturing a razor blade cutting edge, the method including: applying a single coating of a polymer material to the razor blade cutting edge to form a coated blade edge; selecting a temperature profile, where the temperature profile has a temperature and a time, and wherein the temperature profile is selected based on a composition of the razor blade cutting edge; heating the coated blade edge at the temperature and for the time indicated by the selected temperature profile to adhere the polymer material to the razor blade cutting edge; and optionally treating the coated blade edge with a solvent or a mechanical process to partially remove the coating.

Abstract: A razor blade including: a substrate having a tip portion including a tip region, a blade body including a base, and first and second outer sides disposed opposite a split line of the substrate that converge at a tip; and first and second coatings disposed substantially on the first and second outer sides, respectively. Also provided is a method of coating the razor blade, including: applying a first coating to at least a portion of the first outer side; and applying a second coating to at least a portion of the second outer side. The first and second coatings each extend from the tip region toward the base and are substantially different, as compared to each other. One or both of the first and second coatings comprise a plurality of layers of material.

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.

Abstract: A razor blade including: a substrate having a tip portion including a tip region, a blade body including a base, and first and second outer sides disposed opposite a split line of the substrate, in which the first and second outer sides converge at a tip, the first outer side comprises a first coating disposed substantially thereon and extending from the tip region toward the base, and a first portion of the second outer side is substantially free of any coating, the first portion extending from the tip region toward the base or being spaced apart from the tip region and the base. Also provided is a method of coating the razor blade.

Abstract: A method of manufacturing a razor blade cutting edge, the method including: applying a single coating of a polymer material to the razor blade cutting edge to form a coated blade edge; performing a single heating of the coated blade edge at a single temperature of between 620° F. and 795° F. for a predefined time to adhere the polymer material to the razor blade cutting edge wherein the single heating of the coated blade edge comprises one or more heating stages and wherein each of the one or more heating stages is set at the single temperature; and optionally treating the coated blade edge with a solvent or a mechanical process to partially remove the coating. Also provided is a razor blade cutting edge produced according to the disclosed method.

Abstract: This invention relates to a novel application of a compound of chromium and boron, or the application of chromium boride-based coatings (e.g., CrBn where an atomic percentage of boron ranges from greater than zero atomic percent to less than 100 atomic percent of said compound) to surfaces of razor blades, namely cutting edges. On razor blade edges, these novel coatings are hard, durable, and provide a novel, low cutter force and high-quality coating structure, elevating blade performance, while also simplifying the manufacturing process.
