“…presents the typical XRD patterns of Al-Ti-N films under various negative bias voltages. The main phase was a face-centered cubic (fcc) AlTiN with diffraction peaks of (111), (200), and (222), which were identified within the range of -70 V to -250 V. However, the (200) and (222) peaks with very weak intensities at -70 and -150 V completely disappeared at -250 V. Previous studies have reported that (111) and (200) are the main orientations in TiN-and TiN-based films, and the presence of mixed (111) and (200) orientations is the result of the competitive growth between the surface and strain energies[1,20,21]. The (200) orientation with a minimum surface energy was expected when the films were deposited at a low thickness.…”

“…TiN and TiN-based films are widely used as protective material for cutting tools, molds, and mechanical components in many industries [1,2]. Among these films, TiAlN films are increasingly drawing attention because of their superior hardness, advanced wear, and oxidation-resistance properties compared with conventional binary transition-metal nitride films, such as TiN and CrN [3].…”

In this study, we systematically investigated the effects of negative bias voltage on the composition, deposition efficiency, microstructure, and mechanical properties of multi-arc ion plated (MAIP) AlTiN films. The films were deposited on high-speed steel substrates by MAIP at various negative bias voltages. The results indicated that the Al content [Al/(Al+Ti) ratio] and the deposition efficiency were significantly altered by the application of negative bias voltages. X-ray photoelectron spectroscopy analysis showed that the AlTiN films were composed of TiN and Al-N bonds. The macroparticles (MPs) on the film surface decreased with increasing negative bias voltage. We also discussed the different types of MPs found on the films and their influence on the process of determining the hardness of the films. The microhardness of the films depends on the negative bias voltages. The films deposited at-250 V exhibited a maximum hardness of ~45 GPa. The adhesion and frictional tests revealed that the film deposited at-150 V demonstrated the highest cracking resistance, the best adhesion under a critical load of 78 N, highest adhesion strength, and the lowest and stablest coefficient of friction at 0.23.

“…In the work presented by Chetan et al [85], the wear behavior of PVD TiN-coated carbide inserts during the machining of Nimonic 90 and Ti6Al4V super-alloys under dry and MQL conditions is studied. The authors determined that the main mechanism for the wear of the coating during the machining of Nimonic 90 alloy was the abrasive wear and nose fracture, which caused the catastrophic failure of the tool.…”

Turning continues to be the largest segment of the machining industry, which highlights the continued demand for turned parts and the overall improvement of the process. The turning process has seen quite an evolution, from basic lathes using solid tools, to complex CNC (Computer Numerical Control) multi-process machines, using, for the most part, coated inserts and coated tools. These coatings have proven to be a significant step in the production of high-quality parts and a higher tool life that have captivated the industry. Continuous improvement to turning coated tools has been made, with many researches focusing on the optimization of turning processes that use coated tools. In the present paper, a presentation of various recently published papers on this subject is going to be made, mentioning the various types of coatings that have recently been used in the turning process, the turning of hard to machine materials, such as titanium alloys and Inconel, as well as the interaction of these coatings with the turned surfaces, the wear patterns that these coatings suffer during the turning of materials and relating these wear mechanisms to the coated tool’s life expectancy. Some lubrication conditions present a more sustainable alternative to current methods used in the turning process; the employment of coated tool inserts under these conditions is a current popular research topic, as there is a focus on opting for more eco-friendly machining options.

“…In these techniques, the oil and emulsion mist formation parameters play an important role. The researches [15,16] revealed that the lower droplets can penetrate the cutting zone in a better way (MQL method), and enable the faster heat dissipation from the cutting zone (MQCL method) [17,18].…”

Abstract. This paper describes the wear features of indexable carbide P25 inserts when turning C45 steel with cutting speeds of 250450 m/min in dry cutting conditions and in the presence of an emulsion mist (MQCL method). As the active component of the emulsion mist 5%, the aqueous emulsion of EMULGOL concentrate was used. While analyzing the size, shape and formation dynamics of tool wear, the larger dimensions were found for dry cutting. The statistical analysis of results allowed calculating the dependencies to determine the wear rates. The SEM analysis revealed significant oxygen contents at the contact areas that are due to high temperatures in the cutting zone. When cutting with the emulsion mist the presence of phosphorus and copper entering in EMULGOL concentrate was fixed directly on the wear areas. It suggests the possibility of using compounds included in the emulsion mist to form AW and EP films at the contact areas in the cutting zone.
