Device and process for realizing amorphous metal continuous wire cladding by virtue of extrusion

Abstract

The invention discloses a device and a process for realizing amorphous metal continuous wire cladding by virtue of extrusion. The device comprises a wire traction device, an extrusion convex die, an extrusion cylinder, an extrusion concave die and a setting cover, wherein the size of the extrusion cylinder is matched with that of the extrusion convex die; the extrusion cylinder is fixedly connected with the extrusion concave die; the extrusion concave die is fixedly connected with the setting cover; the extrusion cylinder, the extrusion concave die and the setting cover define an extrusion convex die channel, a blank chamber, a shunt chamber, a welding chamber and a forming chamber; a cooling gas spray pipe is arranged at an outlet of the forming chamber; a wire inlet is formed in the wall of the extrusion concave die; a section of wire channel is formed in each of the die body and the die core; a blank shunt chamber is formed in the periphery of the die core and is communicated with the blank chamber; and blanks and wires are mixed and coated in the welding chamber. According to the device and process disclosed by the invention, the surfaces of the wires are coated with amorphous metals, and the surface quality of the wires is improved, so that the wires have excellent corrosion resistance and wear resistance, the application range of the wires is widened, and the service lives of the wires are prolonged.

Description

technical field [0001] The invention relates to an extrusion forming process of an amorphous metal glass, and belongs to the technical field of amorphous metal forming. Background technique [0002] Metallic glasses, also known as amorphous alloys, have the advantages of metals and glasses while overcoming their respective disadvantages due to their unique disordered microstructure. Glass is fragile and has no ductility; but metallic glass is stronger than steel, harder than high-hard tool steel, and has certain toughness and rigidity. Therefore, people call metallic glass "unbreakable and unbreakable". The King of Glass". Amorphous alloys have good mechanical, physical and chemical properties such as high strength, high hardness, good wear resistance and corrosion resistance, which determine their wide application fields and broad application prospects. [0003] Zirconium-based amorphous has lower requirements on the limit cooling rate, and a complete amorphous structure ...

AI Technical Summary

Problems solved by technology

[0004] Amorphous alloys have high strength, high hardness, excellent wear resistance and corrosion resistance, and the surface is bright and beautiful, but the price of amorphous alloys is higher

Brass, steel, thermosetting plastics and other materials are much cheaper than amorphous alloys, but some of their physical and chemical properties are much worse than amorphous alloys
