Abstract Mechanical machining of brittle material is difficult due to generation of fracture or cracks on machined surfaces. Glassy carbon (GC) is a brittle carbon material having outstanding mechanical and chemical characteristics making it suitable for use in glass molds. However, brittleness of GC makes its machining complicated and difficult. In order to fabricate GC surfaces with minimum cracks, hybrid machining processes utilizing electrochemical oxidation have been proposed. In the present study, a new, mixed acidic electrolyte incorporating a chemical oxidizer was utilized to improve the material removal rate of electrochemical oxidation assisted machining. Machining experiments were conducted to evaluate and to confirm the effect of the oxidizer-mixed electrolyte on material removal.

化学氧化剂对电化学氧化辅助加工材料去除率的影响

摘要 脆性材料的机械加工由于加工表面产生断裂或裂纹而困难重重。玻碳 (GC) 是一种脆性碳材料，具有出色的机械和化学特性，适用于玻璃模具。然而，GC的脆性使其加工复杂且困难。为了制造具有最小裂纹的 GC 表面，已经提出了利用电化学氧化的混合加工工艺。在本研究中，一种新的混合酸性电解液加入了化学氧化剂，用于提高电化学氧化辅助加工的材料去除率。进行加工实验以评估和确认氧化剂混合电解质对材料去除的影响。
