As a nontraditional machining process, electrochemical discharge machining (ECDM) can apply to hard and brittle materials such as glass and ceramic. Improvement of process efficiency is an important topic that has been addressed in many investigations using various techniques such as magnetic field and ultrasonic vibrations.

Nano particles are new and advanced materials that can be dispersed in a fluid to obtain a nano fluid with desirable specifications. This method can be implemented in the ECDM process by the application of the nano electrolyte. Nano electrolyte can present enhanced properties, in particular enhanced electrical and thermal conductivities which lead to more powerful discharges and greater material removal.

In order to study the variation of discharge physics, consequent captures from discharges were taken. Besides using current signal diagrams, larger numbers of discharges were found using nano electrolytes. Results of hole depth showed that both Cu and Al₂O₃ nano electrolytes improved the hole depth as 21.1% and 18.7%, respectively. An undesirable effect of nano electrolyte was observed on the entrance overcut, which raised 8.3% and 10.7% using Cu and Al₂O₃ nano electrolytes, respectively, in comparison to the simple electrolyte. This drawback is negligible compared to the significant improvement of hole depth. SEM images of tool wear showed larger molten materials on the tool main edges by the application of nano electrolyte.

作为一种非传统的加工工艺，电化学放电加工（ECDM）可以应用于坚硬和易碎的材料，例如玻璃和陶瓷。处理效率的提高是一个重要的课题，在使用各种技术（例如磁场和超声振动）的许多研究中已经解决了这一问题。

纳米颗粒是可以分散在流体中以获得具有期望规格的纳米流体的新的先进材料。该方法可通过应用纳米电解质在ECDM工艺中实施。纳米电解质可以表现出增强的性能，特别是增强的电导率和导热率，这导致更强大的放电和更大的材料去除率。

为了研究放电物理的变化，需要从放电中捕获。除了使用电流信号图之外，使用纳米电解质还发现了大量放电。孔深度的结果表明，Cu和Al ₂ O ₃纳米电解质均改善了孔深度，分别为21.1％和18.7％。观察到纳米电解质对入口过切的不良影响，与简单电解质相比，使用Cu和Al ₂ O ₃纳米电解质分别提高了8.3％和10.7％。与孔深度的显着改善相比，该缺陷可以忽略不计。刀具磨损的SEM图像显示，通过应用纳米电解质，刀具主边缘上的熔融材料更大。
