所谓电火花强化工艺是通过火花放电在工件表面形成特殊性能的合金层,以强化工件表面。该工艺已被列为国家经委“六五”期间的重点推广项目。“机械工业部电火花强化工艺及应用技术经验交流会”于去年年底在苏州召开,会上交流了该工艺机理的研究成果和实际应用经验。株州车辆厂用于 C62A 型敞车的下侧门、中门和侧柱的大型压型模具强化,模具寿 The so-called EDM is the spark discharge in the workpiece surface to form a special alloy layer to enhance the workpiece surface. The process has been listed as a key promotion project during the “Sixth Five-Year Plan” period of the State Economic Commission. “Mechanical Industry Department EDM Intensive Technology and Experience Sharing Conference” held in Suzhou at the end of last year, the exchange of the mechanism of the research results and practical experience. Zhuzhou vehicle factory for the C62A gondola under the door, the door and the side of the large-scale compression mold strengthening, mold life
