许多金属零件或工具需要在表面刻上文不清晰或效率低的缺点,尤其对高强度、高硬度或簿壁易变形的材料就难以胜任。为了寻求新的刻印技术,60年代初,国外出现了电解刻印并逐步获得推广使用,而国内使用较晚且范围不大,本文对电解刻印作一简介,以利推广。 Many metal parts or tools need to be inscribed on the surface unclear or inefficient shortcomings, especially for high strength, high hardness or wall deformation of the material is not competent. In order to seek new engraving technology, in the early 1960s, there appeared electrolytic engraving in foreign countries and gradually gained popularization and use. However, the domestic use was relatively late and not large in scope. This essay made an introduction to electrolytic engraving to facilitate the promotion.
