“…The appropriate form of the structure and properties of the coating mentioned above occurred as a result of optimization of deposition conditions and choice of the coating material. HRTEM examination of the AlCrN and CrCN showed that the coatings consisted of fine crystallites (Figures 8c and 9c), which corresponds to the results achieved by earlier investigations [17,28,29].…”

The paper presents results of the investigation of the AlCrN and AlCrN + CrCN coatings, deposited by arc evaporation method on the austenitic steel substrate. Topography studies performed with the use of AFM showed that the roughness value was 24 nm for AlCrN and 14 nm for CrCN. Chemical analysis carried out with energy dispersive X-rays spectroscopy confirmed the chemical composition of the coatings. Transmission electron microscopy (TEM) investigations showed a column structure of AlCrN and CrCN layers with a width in the range of 10–200 nm. Tribological properties analyzed using a scratch test and ball-on-disc method showed a good adhesion of the coatings to the substrate (LC2 is 40 and 46 N for AlCrN and AlCrN + CrCN, respectively) and its high wear resistance; the use of an additional CrCN layers caused a decrease in the friction coefficient by 19%. Structure modification of the AlCrN + CrCN coating system and the related improvement in its mechanical and tribological properties allowed increasing the lifetime of the coated elements. The original approach was to produce a dual-layer coating, consisting of an internal, hard AlCrN layer and an external layer of CrCN, providing good tribological properties, as well as an appropriate forming of the transition zone between the layers.

“…References [65,66] reported Lc2 values of around 80-90 N for high-speed steel substrates coated by cathodic arc evaporation PVD (AlTiN and AlCrN, respectively), while [67] presented Lc2 values of 30 N for multilayer Ti/TiAlN/TiAlCN coatings deposited on tool steels by magnetron sputtering. Many other studies showed Lc2 values from 50 N to 80 N for duplex (nitriding + PVD) hard coatings deposited on tool steels [1,[68][69][70]. Furthermore, the values obtained in this study are similar, and even higher in some cases, to those reported for novel PVD techniques such as hybrid PVD [25,71] and closed-field unbalanced magnetron sputtering ion plating (CFUMSIP) [53,61], which presented adhesion strength values up to 116 N and 143 N, respectively.…”

“…Comparing the results of this study with those observed in other studies, it can be seen that the critical load values obtained in the scratch tests are higher than those reported in studies that used cathodic arc techniques [65,66] or duplex treatments [68][69][70]. Furthermore, the adhesion properties observed in this work are even higher than those reported in studies that use novel PVD techniques such as hybrid PVD or closed field unbalanced magnetron sputtering ion plating (CFUMSIP) [25,61,71].…”

Improved Adhesion and Tribological Properties of AlTiN-TiSiN Coatings Deposited by DCMS and HiPIMS on Nitrided Tool Steels

et al. 2021

Hard coatings, such as AlTiN-TiSiN, deposited by Physical Vapor Deposition (PVD) techniques are widely used in industrial applications to protect and increase the lifetime of industrial components, such as cutting tools, dies, and forming tools. Despite their great properties, such as high hardness and wear and oxidation resistance, they are limited in cases of severe conditions due to the poor adhesion between the coating and the substrate. Duplex treatments have commonly been used to improve the adhesive properties of PVD coatings, especially those of the cathodic arc evaporation type. The purpose of this study is to achieve coatings with the good properties of the Magnetron Sputtering processes but with higher adhesion than that achieved with these techniques, thus achieving coatings that can be used under the most severe conditions. In this work, an AlTiN-TiSiN coating was deposited by a combination of DC Magnetron Sputtering (DCMS) and High-Power Impulse Magnetron Sputtering (HiPIMS) after a gas nitriding pretreatment on 1.2379 and Vanadis 4 tool steels. Mechanical (ultra-microhardness and scratch tests) and tribological tests were carried out to study the improvement in the properties of the coating. Duplex-treated samples showed improved adhesion between the coating and the substrate, with second critical load (Lc2) values greater than 100 N. Furthermore, they showed great toughness and wear resistance. These results show that this type of coating technique could be used in the most extreme applications and that they can compete with other techniques and coatings that to date they have not been able to compete with.
