“…A promising way of reducing the amount of used lubricants and increasing wear resistance of tools is a combining technology of surface texturing and protective coating, which have been already proven in different applications [12,13]. It was proven that the combination of hard coatings on the tools for high-performance cutting and sheet-forming dies with additional surface texturing improve tool properties [14][15][16][17]. Due to the local increase of mixed lubrication film thickness, surface texturing can also lead to a significant increase of contact fatigue life [18].…”

The aim of this research was to investigate the influence of laser surface texturing sequence on the fatigue properties of cold-work tool steel. For this reason, polished hourglass-type test specimens made from cold-work tool steel (K890) were surface textured using laser texturing. Surface textures were introduced before and after hard coating deposition (TiAlN) with the aim to investigate the sequence of surface-texturing process. It was found that coating deposition prolongs the fatigue life. The fatigue life behaviour can be influenced also by the sequence of surface texturing. In the case when laser texturing is done after coating deposition, it suffers in fatigue life properties. From a lower magnification, a fractured surface looks like a quasi-ductile fracture, but a closer look reveals that there is very little plastic deformation and some small flat regions can be seen with clear evidence of a brittle fracture mechanism with cleavage. Due to low fracture toughness of investigated steel, no fatigue striations of crack growth steps were found on the fractured surfaces.

“…Most of the studies prepared patterned films by producing patterns on the film surface or depositing films on the patterned surface . Currently, there is an innovative method called masked deposition, which produces the pattern and the film simultaneously, and does not cause film damage . This paper aims to study the effect of the stripe interspace and applied load on the tribological behavior of the stripe patterned TiN films deposited on the surface of H13 steel using a mask plate by a FCVAD technique, carried out by a pin‐on‐disk tribometer under lubricated conditions.…”

This paper describes an experimental investigation into the influence of the stripe interspace and applied load on the tribological behavior of stripe patterned TiN films. The stripe patterned TiN films are deposited on an H13 steel surface by masked deposition with the filtered cathodic vacuum arc discharge (FCVAD) technique. The surface micro morphology, chemical composition, crystal structure, and mechanical properties of the films is characterized using 3D white light interferometry, scanning electron microscopy (SEM), X-ray diffractometry (XRD), and a nano-indentation tester, respectively. The tribological performance of patterned TiN is measured using a UMT-5 tribometer, and the friction and wear mechanisms are analyzed, compared with that of the full TiN film and H13 steel substrate. The results show that the stripe patterned TiN films has better tribological properties than the full TiN film. These results are attributed to the synergistic effect between the surface pattern and the TiN film. The stripe interspace and the applied load has a more significant effect on the wear rate of the stripe patterned TiN films than the coefficient of friction of their friction pairs. A further study, however, is needed to analyze the relationship between the applied load and the wear rates of the stripe patterned TiN films.

“…The development of the latter approach is the vacuum deposition of multilayer and discrete coatings [1, 7,8] to improve their adhesion strength, wear-and impact-resistance, and to decrease the stress-strain state in the tool-coating system. An example is a vacuum-arc three-layer coating Al 2 O 3 -NbN-Ti/Nb on a CT made of cBNbased PSHM [7].…”

The effect of cutting ShKh15 hardened steel on the element and phase composition of the surface layer of the coating deposited on the cBN-based tool is studied. The microstructure and oxidation kinetics of the surface layer of the AlN-Ti(Cr)B 2 magnetron coating are investigated during both formation and turning. The coating is formed by HF magnetron sputtering of an AlN-Ti(Cr)B 2 target. The formation of a two-layer tribofilm with a nanosize outer layer is examined. The phase composition of the tribofilm is determined using layer-by-layer Auger analysis. Its outer nanosize layer is a glass-like phase in the form of limited solid solutions based on Al 2 O 3 oxides and playing a role of solid lubricant. As the cutting speed is increased, the wear rate for the coated tool decreases compared with the uncoated tool.
