Abstract

A research method combining plasma-electrochemical corrosion multi-field coupled simulation and discharge/dissolution experiments was used to reveal the material removal mechanism of electrochemical electric arc machining (ECEAM). A jet-based plasma-electrochemical corrosion multi-field coupling model was established to describe the arc-breaking, heat-transfer, and dissolution processes under the jet electrolyte, as well as the material removal behavior of dissolution/discharge alternation. A single discharge/dissolution experiment with a constant feed rate was designed to verify the reliability of the simulation results and explain the influence mechanism and sensitivity factors of the discharge/dissolution action ratio. Continuous discharge/dissolution experiment was carried out to construct the linkage between the single discharge/dissolution of material and the material surface removal process in order to comprehensively elaborate the material removal mechanism of ECEAM.

电化学电弧加工材料去除行为及影响机理研究

采用等离子体-电化学腐蚀多场耦合模拟和放电/溶解实验相结合的研究方法，揭示了电化学电弧加工（ECEAM）材料去除机理。建立了基于射流的等离子体-电化学腐蚀多场耦合模型，描述了射流电解液作用下的断弧、传热和溶解过程，以及溶解/放电交替的材料去除行为。为了验证模拟结果的可靠性，设计了恒定进料速率的单次出溶实验，并解释了出溶作用比的影响机理和敏感因素。通过连续放电/溶解实验，构建材料单次放电/溶解与材料表面去除过程之间的联系，全面阐述ECEAM的材料去除机理。

期刊介绍： International Communications in Heat and Mass Transfer serves as a world forum for the rapid dissemination of new ideas, new measurement techniques, preliminary findings of ongoing investigations, discussions, and criticisms in the field of heat and mass transfer. Two types of manuscript will be considered for publication: communications (short reports of new work or discussions of work which has already been published) and summaries (abstracts of reports, theses or manuscripts which are too long for publication in full). Together with its companion publication, International Journal of Heat and Mass Transfer, with which it shares the same Board of Editors, this journal is read by research workers and engineers throughout the world.
