碳纳米管具有很高的机械性能和电性能，特别是高导电性。利用电火花加工中的这些特性，将单壁碳纳米管与介质流体混合，分析了模具中广泛使用的Inconel 825的表面特性。碳纳米管既能吸收材料放电产生的热量，又能最大限度地减少工件中白层的形成。实验结果表明，由于放电能量的影响，电火花加工后的表面织构明显增加。通过在低脉冲能量下设置机器参数，可以获得良好的加工纳米级表面光洁度。微裂纹的表面粗糙度和深度与输入功率，尤其是输入电流成正比。此外，AFM测试获得了关于表面形貌的信息，这在电火花加工的Inconel 825的后处理中尤为重要。采用方差分析和f检验确定了影响表面粗糙度的显著参数。
A carbon nanotube has high mechanical and electrical properties, and specifically, high electrical conductivity. By using these properties in Electrical Discharge Machining, the single-wall carbon nanotube is mixed with dielectric fluid to analyse the surface characteristics of Inconel 825, which is very much used in moulds and dies. Carbon nanotube will absorb the heat from electrically discharged material and also minimize the white layer formation in the work piece. Experimental results indicate that the surface texture after electrical discharge machining (EDM) is increased very much due to discharge energy. An excellent machined nanolevel surface finish can be obtained by setting the machine parameters at low pulse energy. The surface roughness and the depth of the microcracks were proportional to the power input, especially the input current. Furthermore, the AFM tests yielded information about the surface morphology which is particularly important in the post treatment of Inconel 825 machined by EDM. Analysis of variance andFtest were used to determine the significant parameter affecting the surface roughness.
