“…Examples include ultrasonic assistance and magnetic field adjustment. Chen [5] introduced a novel technique called ultrasonic assisted electrolytic plasma polishing (UEPP), which enhances polishing efficiency by approximately 30 %. Furthermore, the exploration of magnetic-electrolytic plasma polishing (MEPP) is still in its early stages.…”

Considering that the regulating physical mechanism of the magnetic field on electrolytic plasma is insufficient, this study introduces a plasma discharge model to demonstrate its effect on material removal in magnetic-electrolytic plasma polishing. Firstly, we establish a mathematical model to describe plasma discharge induced by electron collision. The Boltzmann kinematic equations are employed to elucidate the physical dynamics of electrons and their momentum distribution function during ionization collisions. Secondly, we derive the surface material removal equation based on the instantaneous high-temperature melting of plasma discharge and establish the corresponding boundary conditions for simulation calculations. Subsequently, we conduct electromagnetic plasma polishing experiments under varying magnetic field intensities using TA1 titanium alloy as the test material. Our simulation results demonstrate that the magnetic field enhances the spatial electric field formed by the uneven distribution of ion electrons, expediting the plasma discharge process towards the anode and generating interference currents to counterbalance the required material removal current. Experimental data is provided to validate the model, consistently revealing a positive correlation between circuit current and material removal rate. The research demonstrates the rationality and reliability of the material removal model for plasma discharge, offering a fundamental understanding of electromagnetic plasma polishing.

“…In recent years, some researchers tried to find out some technological methods to remove the burrs/bulges effects. Polishing technology is the most effective method for global and local planarization of the wafer, which is widely used in the manufacturing fields of LED substrates, chips and high-end integrated circuits (Chen et al , 2022; Yadav et al , 2023). Inspired by this, some tentative researches have been carried out about the burrs/bulges removing on the textured surface.…”

Purpose The purpose of this study is to further improve the performance of surface texture, the chemical polishing method was introduced and the effect of it on the surface morphology and tribological properties of the surface texture was investigated. Design/methodology/approach The surface texture was processed on the surface of 304 stainless steel with laser technology in air medium. Hydrochloric acid solution (pH 2.4 ± 0.05) was selected and used to soak the prepared texture samples for 12 h. The surface morphology and elemental content of the samples were measured with the white light interferometry, SEM and EDS. To obtain the effect of acid corrosion on the tribological properties of textured surfaces, the samples were tested under dry friction and oil lubrication conditions. Findings The detailed study shows that the melt and burr of surface texture produced with laser processing was reduced due to the corrosion effect of hydrochloric acid. Therefore, the better interfacial tribological properties was obtained due to the improvement of surface-textured morphology. Originality/value The main contribution of this work is to provide a new reference for improving surface texture quality. It also lays a foundation for improving the tribological properties of the textured interface.

“…Ultrasonic-assisted welding is one of the important applications of ultrasonic technology with a high frequency (15 kHz to 40 kHz) and a low amplitude [2]. Different kinds of ultrasonic vibration-assisted machining processes, such as milling [3,4], turning [5,6], grinding [7,8], drilling [9,10], deburring [11,12], diamond machining (cutting) [13,14], electrical discharge machining (EDM) [15,16], abrasive water jet machining [17], hybrid laser-and ultrasonic-assisted machining [18,19], and surface finishing [20][21][22], etc., have been developed in recent years. The materials processed by the ultrasonic-assisted machining processes [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22], in general, can be classified as brittle materials, hard-machining metallic materials, composite materials, and non-metallic materials, etc.…”

The inconvenience of conventional wool ball polishing is that the surface finishing process should be equipped with a slurry container. The main objective of this research is to develop an ultrasonic-assisted surface finishing process for STAVAX mold steel on a 5-axis CNC machining center, by using new lab-made rubber polishing balls containing the abrasive aluminum oxide instead of the traditional wool ball polishing. In total, five types (type A to type E) of new rubber-matrixed polishing balls with a composite of nitrile butadiene rubber (NBR), an abrasive of aluminum oxide, and an additive of silicon dioxide have been developed. The performance of the composites with different grain sizes (0.05 μm to 3 μm) and concentrations of the abrasive of aluminum oxide have been investigated. The effects of multiple polishing passes on the surface roughness improvement for the lab-made polishing balls have also been investigated in this study. A surface roughness of Ra 0.027 μm on average was achieved by using the multiple polishing process of E-C-B-A. The volumetric wear of the lab-made polishing balls, using ultrasonic vibration-assisted polishing, can be improved from about 12.64% (type A) to 65.48% (type E) compared with the non-vibration-assisted polishing. The suitable combination of the ultrasonic vibration-assisted polishing parameters were an amplitude of 10 μm, a frequency of 23 kHz, a spindle speed of 5000 rpm, a feed rate of 60 mm/min, a stepover of 20 μm, a penetration depth of 180 μm, and a polishing pass of E-C-B-A, based on the experimental results. The surface roughness improvement on a test carrier with a saddle surface has also been presented by using the ultrasonic vibration-assisted polishing with the lab-made polishing balls.
