“…Spectra 21 and 33 of the tracks F13 and T13 respectively, indicated by point 2 are located in darker regions where there was greater intensity of oxygen. This may be associated with a slight localized oxidation, which was also observed by Souza et al 43 . In these spectra, small intensities of tungsten were also observed, a major element of the chemical composition of the pins, assuming then that there was a small loss of material due to the relative movement of the surfaces.…”

“…In the T13 track, regions that were plastically deformed in the direction of sliding of the pin and craters were observed, resulting from the crack of the asperities joints and subsequent crack of surface material, with plastic deformation and adhesion being the predominant mechanisms in wear 44 . In the study by Souza et al 43 a surface of AISI 4340 steel was submitted to the pin-on-disc test in relative motion with a pin coated by TiAlN where the wear produced was similar to that shown in Figure 10b. According to the authors, wear was considered the most severe.…”

“…Through EDS area analysis (spectra 5 and 11) it was possible to verify the majority of chemical elements present in the composition of the carbide pin, and therefore, there is no clear evidence about the presence of adhesive wear. In a punctual analysis (spectra 7 and 13), pin F13 showed the adhesion of a dark layer composed mainly of iron and oxygen, that is, probably an oxide layer accumulated during the test 43 . In pin T13 it was also found the presence of iron and oxygen, but in a smaller concentration, but no oxide layer was observed.…”

Friction and wear are influenced by the surface conditions of the material, since there is deformation, segregation, generation of oxide films, among others. Roughness is an important characteristic in tribological studies, where the parameters of skewness and kurtosis have greater influence than the conventional parameters R a and R q. This study is aimed to investigate the influence of the parameters of skewness R sk and R ku kurtosis on the surface of the USI AR 360 steel machining by the milling and turning processes in the pin-on-disc sliding wear test. Results showed that surfaces with the same R a and R q could be distinguished by the skewness parameter. Different behaviors were observed in the analysis of friction curves, where the skewness effect showed a tendency to reduce the friction coefficient. It was also observed that the feed marks orientation in relation to the sliding direction can influence the tribological behavior of the surfaces.

“…Table 1 shows that both the AlCrN and AlCrON coatings exhibit maximum wear rates of 4.5 × 10 −16 and 2.7 × 10 −16 m 3 /(N•m) under dry conditions, respectively. Several studies reported the wear resistance of AlCrN coating deposited with various techniques under different testing conditions regarding the different coating applications [43][44][45]. The reasonable wear resistance at 600 • C was observed in cubic AlCrN and AlCrON coatings, and oxynitride coating exhibited improving wear resistance due to the high ability of a coating to resist oxidation and to delay substrate oxidation [24].…”

The AlCrN and AlCrON coatings were deposited on plasma nitrided H13 steels through ion-source-enhanced arc ion plating, and their structures, mechanical properties, thermal stabilities, and tribological properties were investigated. Structural analysis showed that the monolayer AlCrN and AlCrON bilayered coatings were mainly composed of fcc-AlCrN and fcc-AlCrON solid solution phases respectively. Upon the addition of thin AlCrON layer, the hardness of AlCrN/AlCrON coating slightly decreased from about 30.5 GPa to 28.6 GPa, and the thermal stability was improved after annealing at 700 °C. Both coatings exhibited excellent wear resistance at room temperature, while all wear process involved a combination of wear mechanisms, including severe abrasion and oxidation at an evaluated temperature. The AlCrON bilayered coating showed better wear resistance than that of AlCrN coating due to a dense anti-oxidation layer and better adhesion at a high temperature, making it suitable for die tool protection coatings.

“…Surface properties of sputtered TiAlN thin film (coating) are critical properties that influence the coating application performance, such as wear-resistance [1]. The surface properties in terms of surface energy relate to the surface roughness and adhesive behavior, which contributes to the tribological applications.…”

A study on the surface morphology of sputtered TiAlN coatings is presented. The coatings were deposited by DC magnetron sputtering on tungsten carbide insert tools. The surface morphology was characterized by using Atomic Force Microscopy (AFM), and the surface roughness was indicated by RMS roughness value. It was observed that the TiAlN coating surface morphology was rough as the negative substrate bias and nitrogen flow rate are increased. The evolution of the sputtered TiAlN coatings surface morphology was due to the competition between particle diffusion and re-scattering effect during the sputtering process. At high negative substrate bias and nitrogen flow rate, the re-scattering effect was prominent, leading to the high roughness of the sputtered TiAlN coating surface.
