Abstract
Use: electric erosion processing by a wire electrode - the tool. Essence of the invention: before calibration to the final diameter a wire electrode from an alloy of copper with the zinc having a jacket from zinc, is consistently subjected to the first deformation with a level of deformation of 40-70 %, diffusion burn-in on air at 460-900°С to form a diffused layer by thickness of 100-300 % of thickness of the jacket, the second deformation also with a level of deformation of 40-70 % in relation to the section received after the first deformation and recrystallization annealing in a nitrogen ambient at 600-850°С. The degree of deformation at calibration is chosen in a range of 10-85 %.
