Abstract

The invention relates to the technical field of amorphous alloy application and particularly relates to an amorphous alloy scalpel and a manufacture method thereof. The scalpel is an amorphous alloy scalpel manufactured by a zirconium-based amorphous alloy, a copper-based amorphous alloy, a titanium-based amorphous alloy, a nickel-based amorphous alloy, a palladium-based amorphous alloy or an iron-based amorphous alloy. The Vickers hardness of the scalpel is 400-600, the yield strength is 1000-3000 MPa, the elastic limit is 2-3%, and the nickel release amount is 0-0.015 mg/cm2/week; the surface of the scalpel is not corroded after a salt spray test is done for 500-2000 hours. The manufacture method comprises the steps of preparing an integral outline shape of the scalpel through a die-cast formation method, and molding the knifepoint part through TPF or RDF to obtain the amorphous alloy scalpel. The amorphous alloy scalpel has the advantages of high precision, high strength, high elasticity, high hardness, scratch-resistance, corrosion-resistance, and sharp and long service life.

Description

technical field [0001] The invention relates to the technical field of application of amorphous alloys, in particular to an amorphous alloy scalpel and a manufacturing method thereof. Background technique [0002] In the prior art, surgical scalpels are usually made of stainless steel or titanium alloys. The scalpels made of stainless steel or titanium alloys have the disadvantages of low structural precision and insufficient sharpness. Limit, hardness, scratch resistance, corrosion resistance and surface finish are not good enough, so its service life is not long. [0003] The utility model patent with the authorized notification number CN2481292Y discloses a nano-diamond thin-film high-frequency scalpel. The nano-diamond thin-film high-frequency scalpel deposits a layer of nano-diamond thin film on the surface of the stainless steel scalpel body. Although this nano-diamond thin-film high-frequency scalpel of the prior art has the advantages of being extremely sharp, not s...
