摘要

采用冷拉拔技术制备超细Ni80Cr20合金丝,探索了电化学法烧头和超景深显微镜辅助穿模方法,开展了直径25.60 μm的超细丝拉拔至21.14 μm的烧头和穿模工艺研究.实验结果表明:采用电解电压为5 V,0.2 mol/L的HCl溶液,烧头时间为1 s,超景深显微镜200倍放大模式,成功拉制直径为21.14 μm的微丝;电化学法可以精确控制烧头电压和时间,同时超景深显微镜可以放大金刚石模具孔径,解决了烧头时间控制不准确和人工穿模的难题,显著提高了穿模效率和成功率.

Abstract

The ultrafine Ni80Cr20 alloy wire was prepared by cold drawing technology.To improve the through-die efficiency in ultrafine Ni80Cr20 alloy wire preparation,we explored a new ultrafine wire corrosion-head and through-die method,by which an electrochemical workstation provided precise corrosion time and a super depth of field microscope magnified apertures of diamond dies.Afterwards,we did experiments on the corrosion-head and through-die process of the 25.60 μm ultrafine Ni80Cr20 alloy wire.The research process was also carried out for the 25.60 μm diameter ultrafine wire cold drawn to 21.14 μm.The experiment results show that the electrolysis with voltage of 5 V,0.2 mol/L HCl solution as electrolyte,a second corrosion time and aperture of die magnified 200 times,successfully prepared the 21.14 μm ultra-fine wire.This method resolves the issue of corrosion-head time inaccuracy and manual through-die difficulty,greatly improves the efficiency and success rate of through-die.
