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%.
