Abstract: The oxidation films formed on the surfaces of wheels played an important role in the grinding performance during the ELID grinding processes, which might prevent further electrolysis and avoid excessive wear of the grinding wheels. And the oxidation film could accommodate a large number of abrasive particles that were dropped due to electrolysis, this made wheel grinding just like the polishing of free abrasive particles, which was beneficial to improve the grinding surface quality. The properties of oxidation film directly affected the grinding efficiency and surface quality of ELID grinding. This paper mainly introduced the formation and characterization of the oxidation films, physical and chemical properties of the oxidation films and influence factors of oxidation film formation. And the next steps of the researches of the oxidation films in ELID grinding were prospected.

摘要: 在线电解修整(ELID)镜面磨削加工中,电解作用会使砂轮表面生成一层具有绝缘作用的氧化膜,该氧化膜可以减缓和阻止进一步电解,避免砂轮损耗过快;同时,氧化膜可容纳、承托大量因电解而脱落的磨粒,使得砂轮的磨削类同游离磨粒的研磨、抛光作用,有利于提高磨削表面质量。氧化膜在整个磨削过程中发挥着至关重要的作用,直接影响着ELID磨削加工表面质量和磨削效率。详细阐述了ELID磨削过程中氧化膜的成膜过程及表征方法、氧化膜的物理/化学特性、氧化膜成膜影响因素等方面的研究进展,并对ELID磨削氧化膜下一步的研究重点进行了展望。
