Abstract: A scale-style micro-texture electrode wire material and a preparation method therefor and use thereof. In particular, the electrode wire material has a scale-style micro-texture layer on the surface, and the electrode wire material comprises: i) an alloy substrate layer as an inner layer; ii) an interdiffusion layer as an intermediate layer; and iii) a plating layer as an outer layer; and a contact angle of the electrode wire material to a cooling liquid is 105-150°. A method for preparing the electrode wire material and a use thereof. Due to the special surface bionic structure, the electrode wire can obviously reduce the cutting resistance and improve the cooling speed, thereby improving the cutting speed and effectively improving the use performance of the electrode wire. The preparation method has the characteristics of simple process and easy for industrial production.

Abstract: A manufacturing method of a textured and coated electrode wire, comprising: selecting a copper-zinc alloy as a core material, preparing, by means of electroplating/hot-dipping, a metal zinc coating on a surface of the wire material, then performing pre-treatment on the coated electrode wire by means of discontinuous diffusion annealing to obtain a coated electrode wire material having a multi-layer structure of Zn/β-brass & γ-brass/α-brass, and then using multiple cold drawing treatments and a stress-relief annealing treatment to modify the electrode wire and obtain a textured and coated electrode wire material. Compared to conventional copper alloy electrode wires and zinc-coated electrode wires, the material has advantages of a fast cutting speed, low cutting cost, low environmental pollution, etc., wherein the cutting speed increases by 12% or more when compared with copper alloy electrode wire, the wire breakage rate during cutting processes decreases by 30%, and the replacement time interval of an ion-exchange resin filter for cooling water increases by 10%.
