“…At 1100 °C, Hardness drops to ~30 GPa for (Ti,Al,Cr)N and (Ti,Al,Nb)N while Hardness of TiAlN decreases to 27.7 ± 0.8 GPa [21]. The critical load (Lc) for recovery spallation during scratching at 900 °C is maximum (118 ± 3) for (Ti,Al,Nb)N, and the parameter hardly changes in comparison with room temperature (120 ± 5), while for TiAlN, there is a significant decrease (from 114 ± 11 at room temperature down to 75 ± 4 at 900 °C) [21]. Thus, the coatings based on nitrides (in particular, TiN, CrN, ZrN, NbN) show rather low thermal stability and resistance to oxidation.…”

Tribology International, 128. pp. 313-Abstract:The paper presents the results of the comparative tests of carbide samples with multilayered nano-structured coatings based on titanium nitrides (Ti-TiN-(Ti,Cr,Al,Si)N) and zirconium nitrides (Zr-ZrN-(Nb,Zr,Cr,Al)N and Zr-ZrN-(Zr,Al,Si)N). The phase composition and microstructure of these coatings were studied. The scratch test method was applied to study the adhesion bond strength to the substrate and the coating fracture patterns. The tribological parameters of the coated samples were studied at temperatures of 450°C-900 °C. The cutting properties of the tools with the coatings under study were investigated in turning AISI 321 steel. Various coating parameter effects on the cutting tool life were studied.

To reduce energy consumption and broaden the scope of application of polyethersulfone/polytetrafluoroethylene (PES/PTFE) coatings, three hybrids have been designed by incorporating PES/PTFE coatings with different contents (0, 10, and 20 wt %) of crosslinking agent consisting of epoxy resin and appropriate curing agent (ER‐CA) in the application as low‐temperature curing PES/PTFE coatings and named as EP‐0, EP‐1, and EP‐2, respectively. The addition of ER‐CA gives rise to satisfactory distribution of PTFE, making PTFE play its roles better and improves barrier properties of the coatings by secondary leveling and its own crosslinking structure, which greatly enhances anticorrosion properties. Compared with EP‐0 and EP‐2, EP‐1 exhibits lower water permeability. Even after long‐term exposure to corrosive environments, EP‐1 still possesses high anticorrosion properties. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48740.

“…32 To a large extent this is due to the changes in the electronic structure and chemical bonding of the transition metal nitrides caused by variations of their elemental composition. Despite the numerous experimental and theoretical investigations of the mechanical properties, 32,35,40 solar selective characteristics, 41,42 oxidation behavior, 32,38,43 biocompatibility 44,45 and thermodynamic stability [46][47][48][49] of different ternary and quaternary TiN-based solutions, the quantitative analysis of the evolution of chemical bonding of these materials at an ab initio level was not thoroughly addressed.

A comprehensive study of the evolution of electronic structure and chemical bonding in disordered Ti 1−x Al x N and Ti 1−x−y Al x Ta y N systems was performed by means of ab initio density functional theory calculations using crystal orbital Hamilton population technique. Progressive changes in the character of interatomic chemical bonding were revealed when sequentially alloyed TiN with Al and Ta. Alloying TiN with Al leads to the change in the Ti-N bonding character from ionic to covalent, whereas Al-N bonds being strongly ionic. The following alloying of Ti 1−x Al x N solid solutions with Ta results in a significant reduction of the ionicity of the Al-N bonds, while retaining the covalency of the Ti-N bonds. In addition, alloying with Ta introduces metallic character of chemical bonding in Ti 1−x−y Al x Ta y N, with the degree of metallicity increasing with growing Ta concentration. The gain in metallicity was found to be provided not only by Ta-Ta bonds, which make the main contribution, but also by Ta-N bonds, which have covalent-metallic character. A strong dependence of bonding energies in Ti 1−x Al x N and Ti 1−x−y Al x Ta y N on local atomic surrounding was found. * To whom correspondence should be addressedTitanium nitride (TiN) is currently used as a structural and functional material in a variety of applications because of its unique properties. 1,2 First of all, TiN has high hardness, wear and corrosion resistance as well as high thermal stability, which are of crucial importance for protective and decorative coatings. 3,4 In addition, it is characterized by good diffusion barrier properties, low electrical resistivity, increased optical reflectance 5,6 and compatibility with complementary metal-oxide-semiconductor (CMOS) processes, that makes it promising for diffusion barrier and gate applications, 7 solar cell 8 and infrared reflector 9,10 applications as well as a coating for electrode materials in lithium-ion batteries. [11][12][13] Recently, TiN thin films were also suggested as alternative plasmonic material, 14-18 exhibiting less loss and providing other practical advantages compared to noble metals. However, easy oxidation of TiN already at temperatures of 500-550 • C, and its inherent brittleness restrict the field of its possible application in extreme thermal and mechanical conditions. 19,20 An effective method of increasing TiN oxidation resistance is its alloying with aluminum. Since aluminum (as titanium) can form an fcc crystal phase, 21 it substitutes for titanium in the crystal lattice of the nitride. The addition of Al to TiN coatings drastically increases their resistance to oxidation (from 500 • C to 800 • C), and also ensures the preservation of high values of hardness and wear resistance at temperatures up to 900-950 • C. [22][23][24] Moreover, due to their variable optical properties TiAlN-based coatings are very promising for photothermal and solar energy applications. 25,26 However, the necessity to enhance the efficiency of photothermal conversion of concentrating solar ...
