“…And there are some pitting holes on the surface of the brazed specimens, which are produced through an electrolyte corrosion of the passivity film resulting from an oxidation of the titanium element. Similar phenomena have been found in other reports 31 . The pitting holes enable the electrolyte to penetrate the inner layer of the brazed wheel, which is beneficial to realize an electrolytic reaction and generate an oxide film on the brazed wheel surface.…”

“…Similar phenomena have been found in other reports. 31 The pitting holes enable the electrolyte to penetrate the inner layer of the brazed wheel, which is beneficial to realize an electrolytic reaction and generate an oxide film on the brazed wheel surface. The results of an energy spectrum analysis show that Mo, P, Na, and Br exist in the oxide film, and are derived from the electrolyte during the electrolysis process.…”

An electrolyte containing carbon microspheres (CMSs) was prepared for electrolytic dressing of a multi‐layer brazed coarse‐grained diamond wheel. And the influence of CMSs on the electrolytic in‐process dressing grinding performance of Si3N4 ceramics with the brazed wheel was investigated. The results indicate that the CMSs can increase the electrolytic capacity of the electrolyte, which increases the thickness of the oxide film formed on the brazed wheel surface, and the worn diamond grit can easily fall off from the bonding matrix. In addition, the CMSs were adsorbed and distributed on the film, which effectively improves its densification and adhesion strength. This thicker and denser oxide film can improve the polishing effect of the brazed wheel. Thus, a better machined surface quality and less subsurface damage of the Si3N4 ceramics can be obtained by the multi‐layer brazed coarse‐grained diamond wheel with electrolyte containing CMSs.

“…modelling the real-time workpiece shape evolution during the ECM process combining a confined electrolyte with a moving electrode, although actual channel machining experimental results have been reported by several research groups [7,11,19]. Recently, Liu et al [20] has proposed a 3D FEM model to describe the jet-ECM of TB6 titanium alloy and clarified the dissolution mechanism. However, due to the complexity of the model, a real-time anode shape evolution was not achieved.…”

“…The material removing rate in the ECMM can be adjusted by controlling the applied current. A wide range of hard yet conductive materials such as bulk metallic glasses [ 4 ], titanium alloys [ 5 ], superalloys [ 6 ], carbide-metals [ 7 , 8 ] can be effectively machined by ECMM. Several configurations of ECMM process such as jet electrochemical machining [ 9 ], scanning micro-electrochemical flow cell based ECMM [ 10 ], wire electrochemical micromachining [ 11 ], a tool-based hybrid laser-ECM [ 12 ] and through-mask electrochemical micro-machining [ 13 ] have been introduced to generate surface microstructures.…”

This paper presents fabrication of complex surficial micro-features employing a cross-innovative hybrid process inspired from lithography and Jet-ECM. The process is referred here as mask electrolyte jet machining (MEJM). MEJM is a non-contact machining process which combines high resolution of lithography and greater flexibility of Jet-ECM. It is a non-contact process which can fabricate variety of microstructures on difficult-to-machine materials without need of expensive tooling. The presented work demonstrates the process performance of this technology by statistical analysis and multivariate kernel density estimation (KDE) based on probabilistic density function. Micro-letters are fabricated as an example of complex surficial structure comprising of multiple intersecting, straight and curved grooves. The processing response is characterized in terms of geometrical size, similarity ratio, and cumulative shape deviation. Experimental results demonstrated that micro letters with good repeatability (minimum SD of shape error ratio 0.297%) and shape accuracy (minimum shape error of 0.039%) can be fabricated with this technology. The results suggest MEJM could be a promising technology for batch manufacturing of surface microstructures with high productivity.
