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.
