“…Titanium is an important structural metal developed in the 1950s. Because of the excellent physicochemical properties such as low density, high intensity, good resistance to causticity, nonmagnetic, etc, it is known as "space and ocean metal" and widely used in aerospace and ocean fields [21]. So developing titanium with superhydrophobic surface can raise the value of material in aircraft and ship.…”

Three different microstructures with line pattern, grid pattern and spot pattern were fabricated on titanium surfaces by nanosecond laser. Scanning electron microscopy (SEM), contact angle measurement, surface roughness gauge and X-ray photoelectron spectroscopy (XPS) analysis were used to characterize and measure the surface morphology, contact angle, surface roughness and chemical composition of titanium after laser processing. The results indicate that the contact angle of titanium surface is 77.8º immediately after laser processing, which shows hydrophilicity, and the contact angle presents a rising tendency with time in general. At steady state, the maximum contact angles for line pattern, grid pattern and spot pattern increased to 157.2º , 153º and 132.5º , respectively. It can be found that the surface wettability has changed from hydrophilicity to hydrophobicity and even to superhydrophobicity. The influence of surface morphology on the surface wettability effects immediately after laser treatment and does not change with time, while the effect of surface chemical composition on the surface wettability will continue from the beginning of laser processing to the stabilization of surface chemical composition. Finally, it can be deduced that the accumulation of carbon on the surface is probably the critical factor to improve the surface hydrophobicity. Therefore, it is concluded that laser-induced modification of surface wettability correlates with surface morphology and surface chemical composition.

“…In category "New experiments", it was investigated in Zhou et al (2015) the improvement of the surface integrity of the material after machined by the process of magnetic abrasion with ultrasonic vibration application, which adds to the method 40% more efficiency. The most important variables on magnetic abrasive finishing process were chosen in Jiao2015 and simulations were done by plotting graphs to determine the better polishment trajectory to be executed on the machining.…”

“…The effects of ultrasonic machining actuation allied to magnetic abrasive finishing in the finalization of titanium workpieces were studied in Zhou et al (2015). The principle of magnetic abrasive finishing is based on the alignment of abrasive material with the magnetic field imposed by the pole (Nd-Fe-B, for greater magnetic force) forming an abrasive brush, that rotates according to the pole.…”

This article guides the reader through the latest publications about non-traditional machining processes, also revealing those which present hybrid methods, developed for promoting bigger efficiency and economic advantage in non-conventional machining execution. There is, also, attention to micromachining, a micrometer scale application in dimensions, but with big prospections in modern industry. International articles published from 2014 to 2019 in knowledge bases of Science Direct, CAPES, MDPI, SAGE and IEEExplore referring to methods and new technologies developed in this field are evaluated. The studies expansion in this segment are necessary since engineering materials or micromachining applications are not well finished by conventional methods and advanced methods can be slow, expensive or even poorly researched since there are no articles that study absolutely all processes. The optimization techniques, however, gives a new vision to maximum utilization possible of the presented techniques.

“…In the finishing of thin aluminum sheet metal, Reference [13] reported that the working gap is the most influencing factor. Recently, vibration-assisted MAFs were studied to enhance further surface quality [14][15][16]. A hybrid method combining fixed abrasives and loose abrasives was employed to finish the internal surfaces [17].…”

This paper investigates the underlying interplay between the key process parameters of magnetic abrasive finishing (MAF) in improving surface quality. The five process parameters considered were the working gap, rotational speed, feed rate, abrasive amount, and abrasive mesh when MAFed independently with two abrasive particles—SiC and Al2O3. A series of experiments were conducted with an in-house built MAF tool. Based on the main effect results, a model predicting roughness reduction was developed. Results show that surface quality improvement and the underlying dominant process parameters seem unique to the abrasive type used. When MAFed with SiC, the abrasive quantity and rotational speed influence the most. On the other hand, when MAFed with Al2O3, the trend is different to SiC, i.e., the abrasive mesh size and the working gap are dominant. The prediction model was well validated by independent experiments, indicating its accuracy in estimating and optimizing the process outcome. MAF is a simple process with a complex interplay between parameters. This is very crucial when abrasive type, size, and amount to be used are concerned, which warrants a deeper investigation in terms of underlying dynamics, interactions, and the deformation of abrasive, magnetic, and workpiece materials.
