摘要: 高质高效切削加工是装备制造领域永恒追求的目标,而工件材料切削加工性是决定加工效率和零件加工质量的根本因素。通过对工件材料表层进行改性处理,使被切除层组织结构与热物理力学性能发生定向转变,成为解决难加工材料切除效率低和加工质量差的重要手段,因此难加工材料的表层改性辅助加工技术在近年来也逐步得到关注。在概括钛合金、高温合金以及高强钢等典型难加工材料切削加工性共性特点基础上,综述了表层改性辅助加工工艺研究进展,归纳总结了能量场改性法、活性介质涂覆法和合金化法等改性处理技术对工件材料表层属性的作用机理,阐述了表层改性处理对材料切削加工性的影响规律,指出了当前改性辅助加工对难加工材料切削加工性改善研究存在的问题。最后,对改性辅助高质高效加工未来研究的重点方向进行了探讨和展望。

Abstract: High quality and high efficiency machining are eternal targets pursued by the manufacturing field, and the machinability of workpiece material is the fundamental factor to determine the machining efficiency and quality. Through treatment on workpiece material with surface modification methods, the microstructure and thermophysical-mechanical properties of the removed layer can be directionally transformed. Then the machinability of the workpiece material can be expected to improve. Therefore, the surface modification assisted machining technology of difficult-to-machine materials has gradually attracted attention in recent years.The machinability characteristics of typical difficult-to-machine materials such as titanium alloy, superalloy, and high strength steel are summarized. Then the state of the art on the surface modification assisted machining on different workpiece materials is reviewed. The mechanism of modification treatment technologies such as energy field method, active medium coating method and alloying method on the surface layer of workpiece material is summarized. The effects of different surface modification on the machinability of treated materials are compared and commented. The existing problems of surface modification technology in improving the machinability of difficult-to-machine materials are clarified. Finally, the future research directions of high quality and high efficiency machining achieved by surface modification treatment are discussed and suggested.
