“…Adhesion of the coatings expressed as a critical force in the scratch test depends on many factors, including the material of the substrate. Thus, comparisons of scratch adhesion data with the literature are limited because most authors have studied the scratch adhesion of AlCrN coatings on various types of steel substrates [31,32,45]. In addition, scratch adhesion depends on the mechanical properties of the coating, namely, its microstructure and chemical composition [8].…”

“…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]. Other ways to improve the properties of AlCrN include modifying the substrate properties, such as by nitriding [31,32], or modifying and tuning the coating deposition process [8,33].…”

“…Although AlCrN coating is commonly used as a protective coating for tools exposed to cyclic dynamic loading, there are only a few comprehensive studies addressing this type of loading [34]. Some studies only partially address impact loading, e.g., comparing cratering after a certain number of impacts [33], the effect of temperature [17], or the effect of substrate nitriding [32]. The aim of the present study is to analyse the lifetime of two sets of AlCrN coatings with different microstructures and mechanical properties under cyclic dynamic loading, as described in [14].…”

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.

“…However, certain PVD coatings, such as TiAlN, AlTiN, AlCrN, and TiSiN/AlCrN, exhibit high hardness (up to 35 GPa), offering excellent wear and fatigue resistance. These coatings demonstrate enhanced performance when deposited on a nitrided substrate [22][23][24][25].…”

In this study, novel surface engineering strategies to improve the wear performance of AISI 4340 were investigated. The strategies were as follows: (i) NiP deposition on a previously nitrided steel substrate, followed by NiP interdiffusion heat treatment at either 400 °C or 610 °C (referred to as duplex treatment); (ii) the deposition of AlCrN PVD coating on NiP layers on a previously nitrided steel substrate (referred to as triplex treatment). Prior to the deposition of AlCrN, the NiP was subjected to the interdiffusion heat treatment at either 400 °C or 610 °C. These strategies were compared with the performance of the AlCrN coating directly applied on nitrided steel. To characterize the microstructural features of each layer, X-ray diffraction (XRD) and scanning electron microscopy (SEM) coupled with energy-dispersive X-ray spectroscopy (EDS) analysis were conducted. We also carried out mechanical and tribological behavior assessments. The tribological tests were carried out using a ball-on-disc tribometer under a constant load of 20 N and a tangential speed of 25 cm/s; cemented carbide spheres with a diameter of 6 mm were the counterpart body. The friction coefficient was continuously monitored throughout the tests. The results reveal that the wear mechanism for the AlCrN coating is predominantly oxidative. The most wear-resistant surface architecture was the one comprising AlCrN over the NiP layer subjected to interdiffusion heat treatment at either 400 °C or 610 °C.
