“…The use of Ta is also being recently researched, as shown in the work presented in Section 1 [27], where various multilayered TiAlTaN-(TiAlN/TaN) with differing layer thicknesses were tested and subsequently characterized. In another recent study carried out by Shang et al [93], the mechanical properties of a multilayered TiAlN/Ta coating are evaluated. The coating consists of three layers, a TiAl layer followed by a TiAlN layer and finally, a Ta layer (Figure 26).…”

“…Furthermore, this element confers the coating with a better thermal stability. Studies such as these [27,93] show that Ta is very beneficial to improve TiAlN-based coating's wear behavior. It is known that multilayered coatings benefit from all the properties of their layers, as seen in the previous study [93], where a Ta layer promoted a lower wear rate for the coating, based on its ductility (primarily).…”

The machining process is still a very relevant process in today’s industry, being used to produce high quality parts for multiple industry sectors. The machining processes are heavily researched, with the focus on the improvement of these processes. One of these process improvements was the creation and implementation of tool coatings in various machining operations. These coatings improved overall process productivity and tool-life, with new coatings being developed for various machining applications. TiAlN coatings are still very present in today’s industry, being used due to its incredible wear behavior at high machining speeds, high mechanical properties, having a high-thermal stability and high corrosion resistance even at high machining temperatures. Novel TiAlN-based coatings doped with Ru, Mo and Ta are currently under investigation, as they show tremendous potential in terms of mechanical properties and wear behavior improvement. With the improvement of deposition technology, recent research seems to focus primarily on the study of nanolayered and nanocomposite TiAlN-based coatings, as the thinner layers improve drastically these coating’s beneficial properties for machining applications. In this review, the recent developments of TiAlN-based coatings are going to be presented, analyzed and their mechanical properties and cutting behavior for the turning and milling processes are compared.

“…The presence of aluminum in the coatings of this type brings about the situation where the service-life temperature of these coatings exceeds 970 K, and in such operating conditions of raised temperature, a layer of Al 2 O 3 is formed on the surface, which forms a diffusive barrier for the atmospheric oxygen. 13,14 Zinc oxide is a semiconductor characterized by a high energy gap (3.4 eV), high exciton binding energy (60 meV) and easy n-type doping. 15,16 Zinc oxide, ZnO, obtained with the use of the ALD technique on a sialonceramic substrate enables the polarization of this substrate during the technological process of PVD and, hence, the objective of this paper is to investigate the impact of the ZnO layer obtained with the use of the ALD technique on the adhesion of the hybrid coating ALD/PVD of the ZnO/(Ti,Al)N type to the sialon substrate.…”

This paper is an important research contribution to the development of PVD coatings, in particular, on ceramic substrates, which, due to their dielectric properties, are difficult materials to coat using this technique. In order to satisfy the desired expectations relating to the PVD coatings, one of the basic properties must be provided for, the adherence to the substrate. The main aim of this research is to investigate the structure and mechanical properties of the coatings deposited in a hybrid process, comprising the atomic-layer deposition (ALD) and cathodic-arc evaporation (CAE-PVD) on sintered carbides and multipoint ceramic cutting tools. The concept of this research study involves an execution and investigation of ALD + PVD hybrid coatings on sintered carbides and a sialon-ceramic substrate, and defining the influence of the ALD interlayer on the adherence of the investigated coatings. The critical load Lc, which is the adhesion measure of coats, was determined with the scratch-test method and a tribological test made with a pin-on-disk tester. Observations of the surface topography and wear mechanism were performed using a scanning electron microscope and atomic-force microscopy. The investigation studies showed that an ALD layer considerably improves the adherence of the PVD layer to the tool-ceramic substrate. The research of the coatings on sintered-carbide substrates showed that the adherence of the PVD coating to the substrate deteriorates in the case of applying an ALD interlayer. Keywords: PVD, ALD, hybrid coatings, tool ceramics, sintered carbideŝ lanek je pomemben raziskovalni prispevek k razvoju PVD nanosov, {e posebno na kerami~ni podlagi, ki je zaradi dielektri~nih lastnosti zahteven material za nana{anje s to tehniko. Da bi zadovoljili pri~akovanja na delu s PVD nanosom, je oprijemljivost na podlago osnovna lastnost, na katero je potrebno biti pozoren. Glavni namen raziskave je preiskati strukturo in mehanske lastnosti nanosa, nane{enega s hibridnim postopkom, ki obsega nanos atomskih plasti (ALD) in katodno izparevanje v obloku (CAE-PVD) na sintrane karbide in ve~to~kovno kerami~no rezilno orodje. Koncept te raziskave vklju~uje izvedbo in preiskavo hibridnega nanosa ALD + PVD na podlago iz sintranih karbidov in sialon keramike ter dolo~itev vpliva vmesne plasti ALD na oprijemljivost preiskovanih nanosov. Kriti~na obremenitev Lc, ki je merilo oprijemljivosti nanosov, je bilo dolo~eno s preizkusom razenja in s tribolo{kim preizkusom trn na plo{~i. S pomo~jo vrsti~nega elektronskega mikroskopa in mikroskopa na atomsko silo je bilo izvedeno opazovanje topografije povr{ine in mehanizma obrabe. Izvedene preiskave ka`ejo, da ALD nanos mo~no izbolj{a oprijemljivost PVD nanosa na orodno keramiko. Pri nanosu na podlago iz sintranega karbida je raziskava pokazala, da je pri uporabi ALD vmesne plasti, oprijemljivost PVD nanosa slab{a.

“…It was demonstrated from the GDOES analysis that in the contact zone, from the surface of the coatings, there is a rise in the concentration of the elements that are components of the substrate, with a simultaneous decrease of the concentration of those elements which are components of the coating. As suggested by the authors of earlier works [15][16][17][18][19][20][21][22][23][24][25], this may be due to the presence of a transit zone of a diffusive character between the substrate material and the coating, although we cannot rule out the possibility of simultaneous non-homogeneous evaporation of the material from the surface of the samples during the glow discharge spectrometer tests.…”

“…The rapid development of PVD technology started in the eighties, associated with a wide use of refractory compounds of carbon, nitrogen and boron, in particular with transition metals, as deposition of a thin, hard, anti-wear coating is one of the most important ways to reduce tool wear. Reducing the wear rate and increasing the durability, a low coefficient of thermal conductivity and wear on the effects of high temperature, and in many cases reducing the oxidation and corrosion processes largely determines the use of coatings obtained in the PVD process and, in some cases, the CVD process for coating of tool materials [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25].…”

The paper presents the results on the wear resistance of PVD coatings on cutting inserts made from sintered carbide and sialon ceramics. The exploitative properties of coatings in technological cutting trials were defined in the paper, which also examined the adhesion of coatings to the substrate, the thickness of the coating, and the microhardness. As a result, it was found that isomorphic coating with AlN-h phase of covalent interatomic bonds exhibits much better adhesion to the sialon substrate than isomorphic coating with titanium nitride TiN. These coatings assure the high wear resistance of the coated tools, and the high adhesion combined with the high microhardness and fine-grained structure assure an increase in the exploitative life of the coated tools. In the case of coatings on substrate made from sintered carbide, there was a significant influence on the properties of the tools coated with them as concerns the existence of the diffusion zone between the substrate and the coating.
