Patent

CA 2589273

Colored razor blades are provided. Methods for manufacturing such blades are also provided, including methods involving subjecting a blade material to a hardening process; and, during the hardening process, oxidizing the blade material to form an oxide layer on the blade material. The method also includes quenching the blade material, after the oxidizing step, to initiate martensitic transformation of the blade material, and forming the hardened blade material into a razor blade, the oxide layer providing the razor blade with a colored surface.

L'invention concerne des lames de rasoir colorées ainsi que des procédés de fabrication de celles-ci, y compris des procédés qui comprennent les étapes consistant à: soumettre une matière de lame à un procédé de durcissement; et, pendant le durcissement, oxyder la matière de lame pour former sur celle-ci une couche d'oxyde; tremper la matière de lame après l'étape d'oxydation pour amorcer une transformation martensitique de la matière de lame; et façonner la matière de lame durcie pour obtenir une lame de rasoir, la couche d'oxyde formant sur la lame une surface colorée.
