Abstract

The invention discloses a blackened deposition-coated electromagnetic wire, in which an alloy copper wire is subjected to sol deposition during the process of black oxidation treatment to obtain a black coating. The invention combines the blackening treatment with the sol-coated Working together with the surface of the alloy material, it has a synergistic anti-rust effect and effectively improves the anti-rust performance of the finished material.

Description

technical field [0001] The invention belongs to the field of electromagnetic wires, and in particular relates to a blackened deposition-coated electromagnetic wire and a preparation method thereof. Background technique [0002] Magnet wire is an insulated wire used to manufacture coils or windings in electrical products. Also known as winding wire, magnet wire must meet a variety of usage and manufacturing process requirements. The former includes its shape, specifications, short-term and long-term work at high temperature, and strong vibration and high-speed centrifugal force in some occasions, corona and breakdown resistance under high voltage, and chemical resistance under special atmosphere. Corrosion, etc., the latter includes the requirements of stretching, bending and abrasion during winding and embedding, as well as swelling and erosion during dipping and drying; [0003] In order to improve the antirust ability of steel parts, the surface of steel parts is oxidize...
