电化学光整加工技术与其他加工技术相比，在提高零件使用性能方面具有优势，因而受到关注并得到广泛应用。影响电化学光整加工整平效果的因素很多，其中极间流场是重要因素之一，但是近年来在极间间隙流场特性方面还缺乏研究。分析了电化学光整加工中极间间隙流场的特性，结合气、液两相流在国内外的研究现状，提出了极间电解液流场的研究思路，为极间流场的进一步深入研究提供参考。“,”Compared with other processing techniques,electrochemical finish machining has advantages in improving the service performance of parts,so it is getting more and more attention and widely used. There are several factors influencing electrochemical fin-ish machining,among which the gap between electrodes is one of the most important factor. But recently there is lack of research in in-terelectrode flow field characteristics. The characters of inter-electrode gap flow field in electrochemical finishing were analyzed. Com-bining with present status of research on gas-liquid two phase flow both in China and abroad,the research thought of electrolyte flow field between electrodes was put forward. It provides a reference for further research.
