The micromechanism of the low-cycle fatigue of mono- and multilayer PVD coatings on cutting tools was investigated. Multilayer nanolaminate (TiAlCrSiY)N/(TiAlCr)N and monolayer (TiAlCrSiY)N PVD coatings were deposited on the cemented carbide ball nose end mills. Low-cycle fatigue resistance was studied using the cyclic nanoindentation technique. The obtained results were compared with the behaviour of the polycrystalline silicon reference sample. The fractal analysis of time-resolved curves for indenter penetration depth demonstrated regularities of damage accumulation in the coatings at the early stage of wear. The difference in low-cycle fatigue of the brittle silicon and nitride wear-resistant coatings is shown. It is demonstrated that when distinguished from the single layer (TiAlCrSiY)N coating, the nucleation and growth of microcracks in the multilayer (TiAlCrSiY)N/(TiAlCr)N coating is accompanied by acts of microplastic deformation providing a higher fracture toughness of the multilayer nanolaminate (TiAlCrSiY)N/(TiAlCr)N.

“…Although the model has not been validated under cyclic conditions, several experimental studies with sharper and blunter probe geometries [10][11][12][37][38][39][40] have shown that hard PVD coatings can display a level of fatigue behaviour under cyclic loading. In addition to the coating mechanical properties, the type of cracking observed depends on a range of factors including probe geometry, coating thickness, severity of loading and number of cycles.…”

“…The location of the crack at the top surface at the periphery of the contact predicted by the model has also been seen in experimental studies of repetitive micro-scale impact by spherical indenters with smaller end radii (17-20 µm). For example, Beake, Liskiewicz and co-workers used the recently developed micro-impact technique to investigate the micro-scale impact resistance of hard carbon coatings on hardened tool steel [10,12,37] and PVD nitrides on cemented carbide [11,12,38].…”

“…Multilayer coatings that consist of different nitride layers and composition-gradient interlayers show improved mechanical properties, such as excellent hardness and adhesion strength due to their specific interfaces [ 18 ]. The main factors responsible for improving mechanical and tribological properties include high hardness to elastic modulus ratio, through-thickness composition-gradient properties, resistance to through-thickness cracking by crack deflection between multilayers and adaptive mechanisms from tribo-film formation [ 19 , 20 ].

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.
