Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing.

[0031] The metal wire with improved strength and corrosion resistance of the present invention is provided with a layer of metallic glass coating on the surface of the metal wire body. Metallic glass coating preferably Zr 41.25 Ti 13.75 Ni 10 Cu 12.5 be 22.5 coating, the metal wire body is preferably a copper wire, and the diameter of the metal wire body is 0.2mm--5mm.

[0032] The preparation method of the metallic wire with metallic glass coating of the present invention is,

[0033] 1) First, place the metallic glass ingot in an electric arc furnace filled with inert gas, and use electric arc to repeatedly smelt it to become a liquid metallic glass with uniform composition; the purpose of the inert gas environment is to make the metallic glass not easy to be oxidized. The obtained argon creates a stable environment. At the same time, in order to make the compositi...

Abstract

The invention discloses a metal wire for improving strength and corrosion resistance and a preparation method of the metal wire. A layer of metal glass coating is arranged on the surface of a metal wire main body. The preparation method comprises the following preparation steps of: 1) firstly, putting a metal glass ingot into an electric arc furnace filled with inert gas; continuously smelting the metal glass ingot by using electric arcs so that the metal glass ingot becomes liquid metal glass with uniform components; 2) enabling the metal wire to quickly pass through the liquid metal glass so that a layer of liquid metal glass coating is attached to the metal wire; and 3) quickly cooling the metal wire attached with the liquid metal glass coating so that the liquid metal glass coating forms a metal glass coating. According to the preparation method, the metal glass coating and the metal wire are closely combined without an insect biting effect caused by a potential defect. The mechanical strength and the strain property of a copper wire coated with metal glass alloy are obviously better than those of an uncoated copper wire. The corrosion resistance of the copper wire coated with the metal glass alloy is obviously better than that of the uncoated copper wire.

Description

technical field [0001] The invention relates to metal material coating technology, specifically refers to a wire with a metallic glass coating and a preparation method thereof. The invention can increase the strength and corrosion resistance of the metal wire, and belongs to the fields of condensed matter physics and material science. [0002] Background technique [0003] Metallic glasses are a new class of materials that have attracted intense attention due to their excellent mechanical, physical and chemical properties. The disordered atomic structure of metallic glasses endows them with high strength, low Young's modulus, and high elasticity, and these properties make them promising as functional and structural materials. However, the weak plasticity of metallic glasses at room temperature and the low formability limited to the millimeter scale seriously hinder the application of metallic glasses in real life. With the development of composite metallic glass materials,...
