Abstract

The invention discloses a salt mist-resisting alloy wire and a manufacturing process thereof. The salt mist-resisting alloy wire comprises a steel wire conductor, the outer side of the steel wire conductor is wrapped by a copper plated layer, the outer side of the copper plated layer is wrapped by a nickel plated layer, the outer side of the nickel plated layer is wrapped by a tin plated layer, the thickness size of the tin plated layer is larger than that of the nickel-plated layer, and the outer side of the tin plated layer is wrapped by a polishing film. The manufacturing process specifically comprises the first step of material selecting, the second step of quenching and tempering, the third step of electroplating of the copper plated layer, the fourth step of electroplating of nickelplated layer, the fifth step of electroplating of tin plated layer, and the sixth step of polishing and passivation. By optimizing the production process, clad layers are more uniform and smooth; polishing passivation is adopted, and a polishing film is formed; and under the situation of improving the salt mist corrosion resisting performance, the thickness of the tin plating layer can be appropriately reduced, and therefore the production cost is reduced.

Description

technical field [0001] The invention relates to a salt spray resistant alloy wire and a manufacturing process thereof. Background technique [0002] With the continuous development of science and technology and the continuous improvement of human living standards, the requirements for various materials such as alloy wire tend to be environmentally friendly, multi-functional, high-strength and lightweight. Thanks to the development of global economic integration, many products are exported to all over the world. However, in the marine transportation environment, Cl ions in the marine environment are highly corrosive to metals. Salt spray corrosion is a type of electrochemical corrosion, especially for alloy wires that work in a salt spray environment, which not only requires a smooth appearance, but also has salt spray corrosion resistance. Contents of the invention [0003] The object of the present invention is to provide a salt spray resistant alloy wire and its manufa...
