“…Conformal cracks emerge at 22.5 N (Lc1), followed by recovery spallation at 46 N (Lc2) and buckling spallation at 63 N (Lc3). The nitrided substrate enhances the adhesion of PVD coatings [35]. Finally, Figure 4d,e depict the scratch grooves for the two triplex architectures.…”

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.

“…For this reason, there was no mixing of the coating material and the steel material, nor was the material accumulated on the edges of the scratch. The mechanical and tribological properties of the AlCrN coating and of the AlCrN/FexN duplex coating deposited via PVD arc evaporation have been previously investigated by the author Ramírez-Reyna and his team [27]. They also investigated the effect of a nitriding pretreatment on the mentioned properties.…”

This paper presents the results of research focused on increasing the lifespan of HPDC moulds for casting aluminium alloys by applying duplex PVD coatings in combination with laser texturing the base material before the coatings’ deposition. This article describes the HPDC process and the degradation mechanisms of the moulds that arose during this process. The PVD nanostructured coatings utilised, the methods of their deposition, and the evaluation of their wear resistance are defined in this paper. The surface texturing process is described alongside the description of the analysis of the wear of the functional parts of the mould after decommissioning, which was carried out by visual inspection and optical and light microscopy. Three types of PVD duplex coatings were analysed during our study. The coatings were deposited using the LARC technology method (lateral rotating cathode). Subsequently, the procedure of laser texturing in the form of dimple textures using a laser was proposed. The quality of the coatings was evaluated under tribological conditions by means of the “Ball on disc” method. Based on the experimental results, recommendations for practice are established.

“…However, super-hard ceramic coatings are usually related to low fracture toughness and lower adhesion to the substrate. In particular, some results have shown that AlCrN-based coatings exhibit weak adhesion during scratch and impact tests [8][9][10]. Different methods have been developed to obtain coatings with enhanced hardness and toughness and improved adhesion strength, from the creation of a gradient structure [11], satisfying the requirements of the coating throughout the coating thickness, to a multilayer structure [12], including crack deflection mechanisms [13,14].…”
