“…Almost 20 years ago, the potential of LIPSS for tribological applications was recognized: Yu and Lu reported an improved tribological performance of micrometer sized ripples on NiP (a support material for magnetic data storage elements in computer hard drives), when compared to the flat NiP surface [ 43 ]. In the following years, LIPSS were generated by ultrashort laser pulses on various materials and tested with respect to friction and wear, for instance for nitrides [ 44 , 45 ], carbon materials [ 46 , 47 , 48 , 49 , 50 , 51 ], semiconductors [ 52 ], and metals [ 12 , 53 , 54 , 55 , 56 , 57 ]. Several specific applications were explored, such as the improvement of mechanical seals [ 50 , 51 ], or the optimization of the machining performance of cutting tools [ 58 , 59 , 60 , 61 ].…”

Laser texturing is an emerging technology for generating surface functionalities on basis of optical, mechanical, or chemical properties. Taking benefit of laser sources with ultrashort (fs) pulse durations features outstanding precision of machining and negligible rims or burrs surrounding the laser-irradiation zone. Consequently, additional mechanical or chemical post-processing steps are usually not required for fs-laser surface texturing (fs-LST). This work aimed to provide a bridge between research in the field of tribology and laser materials processing. The paper reviews the current state-of-the-art in fs-LST, with a focus on the tribological performance (friction and wear) of specific self-organized surface structures (so-called ripples, grooves, and spikes) on steel and titanium alloys. On the titanium alloy, specific sickle-shaped hybrid micro-nanostructures were also observed and tribologically tested. Care is taken to identify accompanying effects affecting the materials hardness, superficial oxidation, nano- and microscale topographies, and the role of additives contained in lubricants, such as commercial engine oil.

“…Table 1 lists the cutting conditions. Cutting experiments were performed under wet cutting condition using emulsion type cutting fluid (NEOS Co., Ltd., Finecut CFS-100) supplied at a flow rate of 12.6 L/min, because our previous research [14] confirmed the effect of nano/micro texture is not exerted under dry cutting condition. The anti-adhesions of four types of cutting tools, concretely, NM-1, MS-1, a conventional cutting tool with polished surface, and the cutting tool with combined texture were evaluated.…”

In cutting of aluminum alloys, one of the most serious problems is chip adhesion to cutting tool surface, often leading to tool failure, above all, in dry cutting. To address this problem, we adopted surface engineering approach, namely, a functionalization of tool surfaces by textures. In our previous research, we have developed the DLC-coated cutting tool with nano/micro-textured surfaces and the cutting tool with micro stripe textured surface formed using femtosecond laser technology. Face-milling experiments on aluminum alloys showed that the nano/micro-textured surface suppresses the genesis of adhesion at the atomic level. On the other hand, it was found that micro stripe texture prevents chip adhesion from growing larger even in dry cutting conditions. In this study, a cutting tool with new textured surface combined nano/micro texture and micro stripe texture was developed in order to further improve anti-adhesiveness in cutting of aluminum alloys. As a result, it was confirmed that the combined texture brings excellent anti-adhesion compared to the previously developed tools.

In the cutting processes, improvements of anti-adhesive properties and wear resistance of cutting tools are strongly required for increasing a cutting tool life. In order to meet these requirements, we adopted surface engineering approach, namely, a functionalization of tool surfaces by textures. In our previous researches, we have developed two types of cutting tool with textured surface, namely, cutting tool with nano/micro textured surface and cutting tool with micro stripe textured surface, in the hopes of improving anti-adhesive properties in cutting of aluminum alloys. As a result, we have clarified that the developed tools significantly decrease chip adhesion on the tool surface by a series of face milling experiments for aluminum alloys. In this paper, the previously developed tools with textured surfaces were applied to the cutting of steel material (S53C) and the wear resistances of the textured surfaces were evaluated. As a result, it was found that the micro stripe texture improves the wear resistance significantly. Moreover, the mechanism of improving wear resistance by the textured surface was also discussed.
