“…AlCrN protective coatings are widely used in manufacturing and machining operations with cyclic impacts or dynamic loads, namely drilling, milling, cutting, and punching [14][15][16][17]. Due to the wide range of applications, AlCrN coatings have been the subject of intense research in recent years.…”

“…Their properties that are favourable for practical applications such as high hardness [18], high thermal stability and oxidation resistance [16], abrasion resistance [19], and low coefficient of friction [20] have been studied. These mechanical and tribological properties of the AlCrN system are strongly dependent on the chemical composition and microstructure [21,22], which are related to the sputtering conditions, such as a substrate bias [23], ion flux ratio during deposition [14,24], or the nitrogen content in the case of the reactive sputtering [25]. Currently, the improvement of AlCrN coatings is mainly focused on tuning the coating structure, such as through 2 of 14 alloying [8,26,27], multilayer systems [8,20,28], and gradient coatings [29,30].…”

AlCrN coatings, which are characterized by high hardness and good wear resistance, are often used for drilling, milling, and punching tools. Therefore, the study of the behaviour of these coatings under cyclic impact loading is essential for their optimization. Our previous work has focused on the study of the composition and microstructure of AlCrN coatings prepared using a cathodic arc deposition system with a SCIL® controller that controls the average ion energy per deposited atom (Ed). Two sets of coatings were prepared in two different modes, with a metal target and with a poisoned target. The chemical compositions of the coatings were very similar regardless of their deposition conditions, but the structure and mechanical properties of the coatings depended strongly on Ed. The present work focused on the scratch adhesion and impact wear of these two sets of AlCrN coatings. The lifetimes of both sets of samples under repeated dynamic impacts were tested using a dynamic impact tester with a WC-Co ball. It was shown that the impact behaviour of the coatings prepared in the metallic regime does not depend on the deposition conditions. However, the impact behaviour of the coatings deposited in poisoned mode was improved by increasing Ed.

“…In addition, AlCrN coatings have attracted great interest from researchers and tool manufacturers due to their good toughness, high temperature oxidation resistance and thermal stability. The dissolution of Al in CrN crystals leads to lattice distortion and grain refinement that contributes to excellent mechanical properties [ 12 , 13 ].…”

In tribological applications, the degradation of alloy nitride coatings is an issue of increasing concern. The drawbacks of monolayer hard coatings can be overcome using a multilayer coating system. In this study, single-layer TiAlNbN and multilayer TiAlNbN/AlCrN coatings with AlCrN layer addition into TiAlNbN were prepared by cathodic arc evaporation (CAE). The multilayer TiAlNbN/AlCrN showed B1 NaCl structure, and the columnar structure continued from the bottom interlayer of CrN to the top multilayers without interruption. After AlCrN addition, the TiAlNbN/AlCrN coating consisted of TiAlNbN and AlCrN multilayers with a periodic thickness of 13.2 nm. The layer thicknesses of the TiAlNbN and AlCrN were 7 nm and 6.2 nm, respectively. The template growth of the TiAlNbN and AlCrN sublayers stabilized the cubic phases. The introduction of bottom CrN and the TiAlNbN/CrN transition layers possessed com-position-gradient that improved the adhesion strength of the coatings. The hardness of the deposited TiAlNbN was 30.2 ± 1.3 GPa. The TiAlNbN/AlCrN had higher hardness of 31.7 ± 3.5 GPa and improved tribological performance (wear rate = 8.2 ± 0.6 × 10−7 mm3/Nm) than those of TiAlNbN, which were because the multilayer architecture with AlCrN addition effectively resisted abrasion wear.

“…One of the solutions might be a commonly used AlCrN hard coating which has very good high-temperature properties and a superior wear resistance as compared to often used TiN coating [14]. AlCrN coating is a common protective coating in the tool industry due to its high oxidation resistance and thermal stability [15] providing good tribological characteristics [16].…”

The aim of the study was to investigate effect of Ti/TiB2 composite composition and manufacturing technology parameters on the tribological behaviour of AlCrN coating-composite system. The AlCrN coating was deposited by PVD (Physical Vapour Deposition) method. The composites were manufactured by spark plasma sintering (SPS) from three variants of powders mixtures: Ti with TiB2, Ti6Al4V with TiB2 as well as Ti with B, using (five) different sintering temperatures. For each of the developed coating-composite systems, the wear resistance was evaluated using ball-on-disc SRV tester, at six temperatures (from room temperature up to 900 °C). The results confirmed that high-temperature wear resistance of the coating–substrate combination depends on Ti/TiB2 composite composition and manufacturing technology parameters. In the case of uncoated composite, two processes manage the wear at high temperatures: cracking propagation and surface oxidation. The presence of AlCrN coating on the composite surface protects the surface against deep cracking and surface oxidation. The composites of Group I, sintered at 1250 °C from a mixture of pure Ti and TiB2 (50/50 wt.% ratio) as well as Group III, sintered at 1350 °C from a mixture of pure Ti and B allow the achievement of a satisfactory surface quality, a high adhesion of the PVD coating and moderate wear at high temperatures. However, the composite made of pure Ti and B seems to be a better solution for temperatures exceeding 600 °C.
