Embodiment Construction

[0022] The present invention relates to a novel application in which aluminum magnesium boride (AlMgB 14 , also known as BAM) based ceramic coatings are applied to the surfaces of razor components, and in particular to the cutting edges of razor blades, as described herein. Applicant is unaware that BAM materials are being used or proposed for use with razor blades. The hard and / or low-friction properties of BAM coatings can provide significant benefits on razor blades, as these coatings can improve blade performance and / or simplify the manufacturing process.

[0023] Baseline BAM materials generally contain elemental aluminum, magnesium and boron. The term "BAM" or "BAM material" or "BAM layer" or "AlMgB 14 " or "BAM-based" or "BAM alloy" or "BAM analog" will generally be used herein interchangeably and may denote the matrix material AlMgB 14 As such, derivatives of materials such as metal borides XYB 14 , where X and Y are metal atoms, or by the matrix AlMgB 14 The mate...

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.

Description

technical field [0001] The device relates generally to razor blades, and more specifically to novel coatings on razor blades. Background technique [0002] Current razor blades typically comprise a sharp base such as stainless steel, a hard coating layered over the stainless steel to optimize edge strength, tip shape, wear resistance, etc., and a usually polymeric material such as Telomer to impart lubricity to the soft coating. [0003] It is well known that the combination of a sharp blade profile and a hard and lubricious coating generally defines the performance of the blade element. In general, the interest is coating options that can improve the hardcoat performance of the blade elements and / or enhance the lubricity of the blade. [0004] It would be desirable to optimize blade coatings and / or steps required in blade production while maintaining or improving blade performance. Contents of the invention [0005] According to the present invention, a razor blade dev...
