“…Many electrolytes cause significant oxidation of amorphous alloys, as seen during the electrochemical machining of Fe 65.5 Cr 4 Mo 4 Ga 4 P 12 C 5 B 5.5 in aqueous solutions of NaNO 3 , NaOH, and H 2 SO 4 , all three of which appeared not to be suitable as electrolytes, [ 256 ] or in Zr 57 Ni 20 Al 15 Cu 5.5 Nb 2.5 in aqueous solutions of NaNO 3 . [ 257 ] There can be optimizations to the electrochemical machining process which can reduce or eliminate oxidation, evidenced during the machining of Fe 65.5 Cr 4 Mo 4 Ga 4 P 12 C 5 B 5.5 on an aqueous electrolyte of 0.1 m H 2 SO 4 with up to 0.1 m Fe 2 (SO 4 ) 3 . [ 258 ] Here, the application of very short voltage pulses results in a dissolution process of oxide layers that may be forming during the cutting process.…”

In this review, two interrelated areas are focused on for the development of novel amorphous metallic alloys, namely, materials processing and machine learning techniques for the design of new alloy compositions. Findings, barriers, and opportunities are described, targeting powder production and sintering, additive manufacturing, and postprocessing techniques, followed by the latest developments in artificial intelligence algorithms for both the design of new alloys and for alloy classification tasks.

“…However, research has shown that a nonlinear electrolyte such as sodium nitrate can provide significantly better machining quality than linear electrolyte-like sodium chloride, and this is mainly due to the passivation effect of sodium nitrate [ 19 ]. In order to improve the machining quality of a specific machining object, more scholars choose to optimize machining parameters, such as the machining voltage, duty cycle, impulse frequency, and electrolyte concentration, to achieve better machining quality [ 20 , 21 , 22 , 23 , 24 , 25 , 26 ]. At present, research on cathode materials mainly focus on the application of single cathode material in electrochemical machining, such as brass, copper alloy, or iron alloy, while there has been less research in the field of electrochemical machining [ 27 , 28 , 29 , 30 ].…”

Different cathode materials have different surface chemical components and machining capacities, which may finally result in different machining quality and machining efficiency of workpieces. In this paper, in order to investigate the influence of cathode materials on the electrochemical machining of thin-walled workpiece made of 304 stainless steel, five cylindrical electrodes are used as the target working cathodes of electrochemical machining to conduct experiments and research, including 45# steel, 304 stainless steel, aluminum alloy 6061, brass H62, and tungsten steel YK15. The stray current corrosion, taper, and material removal rate were used as the criteria to evaluate the drilling quality of efficiency of a thin-walled workpiece made of 304 stainless steel. The research results show that from the perspectives of stray current corrosion and taper, aluminum alloy 6061 is an optimal tool cathode, which should be used in the electrochemical machining of thin-walled workpieces made of 304 stainless steel; on the aspect of material removal rate, the 45# steel, 304 stainless steel, and aluminum alloy 6061 present close material removal rates, all of which are higher than that of brass H62 and tungsten steel YK15. Based on comprehensive consideration of both machining quality and machining efficiency, the aluminum alloy 6061 is the best option as the cathode tool in the electrochemical machining of thin-walled workpieces made of 304 stainless steel.

“…With a tungsten electrode with a diameter of 15 μm, the multi-order 3D microstructure was obtained. The microgroove width was 16.8 μm, and the machining precision reached 900 nm [ 13 ]; Meng carried out a series of experiments on Ni-based metallic glass, optimized the experimental parameters, and produced a series of high quality metal glass microstructures, such as a micro curved cantilever beam, micro gear, and micro square helix [ 14 , 15 ]; Cole used signal-noise ratios and analysis of variance to optimize parameters of the electrochemical micromachining process, and the optimal holes with respect to the aspect ratio, surface roughness and the rate of electrochemical micromachining of Zr-based bulk metallic glasses (BMGs) were obtained [ 16 ]. Although the above research has its own achievements in the theory or experiment of EMM, there is still a lack of theoretical mathematical models and experimental research for a certain kind of micro ECM process, such as micro electrochemical drilling, milling or wire micro ECM.…”

Micro electrochemical machining is becoming increasingly important in the microfabrication of metal parts. In this paper, the machining characteristics of micro electrochemical milling with nanosecond pulse were studied. Firstly, a mathematical model for the localization control of micro electrochemical milling with nanosecond pulse was established. Secondly, groups of experiments were conducted on nickel-based superalloy and the effects of parameters such as applied voltage, pulse on time, pulse period, electrolyte concentration and electrode diameter on machining localization and surface roughness were analyzed. Finally, by using the optimized machining parameters, some 2D complex shapes and 3D square cavity structures with good shape precision and good surface quality were successfully obtained. It was proved that the micro electrochemical milling with nanosecond pulse technique is an effective machining method to fabricate metal microstructures.
