Abstract_Chinese:\r针对钛合金这种典型的难于传统机械加工的材料，电解加工能达到“以柔克刚”的目的，是解决钛合金加工难题的首选方案．但是钛存在自钝化的特性，如果使用常规的水基电解液进行钛合金的电解加工，其基体表面会持续生成氧化膜，降低加工精度，甚至导致加工无法进行．为了解决这一技术难点，本文尝试采用以乙二醇作为基体的电解液进行电解加工实验．并通过工艺优化实验探究了行走速度、初始加工间隙、脉冲峰值电压等参数对钛合金微细电解加工效果的影响．通过对比分析加工效果，最终确定出优化的工艺参数，并利用优选参数在钛板基体上加工出TJU 字样，从而实现钛合金微细电解加工．


Abstract_English:\rElectrochemical machining is a preferred method to manufacture difficult-to-cut materials such as titanium alloy. However，titanium is easily passivated. If a conventional water-based electrolyte is used，oxide film will instantly form on the surface，which will reduce the machining accuracy and even lead to the failure of processing. To
solve this technical difficulty，a type of electrolyte based on ethylene glycol was used in this paper. Through the process optimization experiment，the influences of moving rate，initial inter-electrode gap，and pulse potential on the performance of the micro electrolytic machining of titanium alloy were investigated. By comparing and analyzing the machining performance，the optimum technological parameters were determined. Finally，the word“TJU” was processed on the titanium plates using the optimized parameters to confirm the utility of electrochemical micromachining using this ethylene glycol-based electrolyte.
