摘要
局部损伤是零件再制造中常见的一种失效形式,由于损伤情况的多样性,成为企业再制造加工中的一个难点。文中针对零件表面局部损伤的特点和现有修复方法热输入量大、修复效率低和成本高的不足,主要对高能脉冲精密冷补技术、电火花表面强化修复技术和微脉冲电阻焊修复技术的工作原理、应用特点进行了阐述,列举了以上几种技术在金属零件表面修复与再制造中的应用实例。
Local damage is a common failure mode in remanufacturing parts, due to the diversity of the dam- age, it is difficult for companies to remanufaeture. In this paper, based on the characteristics of local damage parts on the surface of the remanufaeturing parts and the lack of available repair methods such as a mass of heat input low efficiency and high repairing cost, the principle and application characteristics of the high-ener- gy pulses of laser-precision cold-welding technology, EDM surface hardening technology and micro-pulse re- sistance welding technology are introduced, at the same time some examples of application are given.
