Abstract

The invention relates to the technical field of application of amorphous alloys and in particular relates to application of an amorphous alloy to preparation of a razor blade and a razor. The strength, elastic limit and Vickers hardness of the razor blade prepared by utilizing the amorphous alloy are respectively 1400-2300MPa, 2-2.5% and 530-600, and the surface of the razor blade is still good and corrosion-free after being subjected to salt spray test for 336-480 hours. The razor comprises a blade holder, a razor rest and the razor blade prepared in application of the amorphous alloy to preparation of the razor blade. Compared with the blades coated with coating materials or on which the coating materials are deposited and the razor blades directly cast by utilizing titanium alloys or stainless steel, the prepared razor blade and razor have excellent strength, elastic limit, Vickers hardness and corrosion resistance and have the advantages of simple production processes, high production efficiency and low production costs.

Description

technical field [0001] The invention relates to the technical field of application of amorphous alloys, in particular to the application of amorphous alloys in preparing shaving blades and shaving knives. Background technique [0002] The shaving blade needs to have the characteristics of sharpness, high hardness, high strength, good elasticity and not easy to deform, so as to meet people's needs and prolong its service life. In addition, the shaving blade is easily corroded or rusted by the external environment due to long-term contact with water and exposure to a humid environment. [0003] However, the strength, hardness, elastic limit and corrosion resistance of the shaving blades in the prior art are not ideal. In the prior art, in order to improve the strength, hardness and corrosion resistance of the shaving blade, coating or depositing coating materials, such as polymer material coating or diamond coating, are often used on the substrate of the shaving blade. This ...
