“…In addition, the intermediate layer can be used to block the heat flow from frictional heat sources to the substrate and the inter-diffusion between the tool and the workpiece material (barrier function). This layer can be used as a sensor which monitors the thermal and mechanical stress on the cutting tool directly in the cutting process in order to diagnose tool conditions, [11][12][20][21][22][23].…”

In coated tools, the grain boundaries and coating layers are areas of intense energy dissipation, which hardens the coating material by increasing its toughness and its resistance to the formation and development of cracks. An increase in the efficiency of the coatings was achieved by applying nano-dispersed multilayer composite structure. This paper proposes using nano-scale multilayer composite coating based on TiN-CrN compound to improve thermal stability, where, barrier layers based on ZrNbN have been introduced. The ZrNbN barrier does not interact with TiN and CrN at temperatures around 1000°C. The influence of process parameters of the filtered cathodic vacuum arc deposition on the composition, structure and properties of the coatings based on variation of TiAlN-ZrNbN-CrN was analyzed. The results presented here show that the hardness of the developed coatings was as high as 38 GPa. Subsequently, the carbide tools used in this study with the new coatings had an increased lifetime of 1.5-2.0 times compared to tools with commercial coatings. The coated tools were tested in turning and milling of steels, nickel and titanium alloys.

Angular absorptance and thermal degradation analysis of TiB₂/Ti(B,N)/SiON/SiO₂ multilayer solar absorber coating

Multilayer solar selective absorber coatings have been developed in the last few decades. The thermal stability in terms of microstructure gives an insightful understanding of the optical properties of such coatings. In this context, we extensively utilized transmission electron microscopy (TEM) analysis to establish the thermal stability of TiB 2 /Ti(B,N)/SiON/SiO 2 coating, under thermal cycling/continuous heating to 500 • C in vacuum for 250 h. In particular, this work reports the variation in the solar absorptance of TiB 2 /Ti(B,N)/SiON/SiO 2 coating with different angles of incidence of the solar radiation. Extensive analysis using the TEM technique reveals the presence of oxide interlayers that act as diffusion barrier layers to enhance the thermal stability of the coating.Computational simulation using SCOUT software validates the measured reflectance spectrum of the developed multilayer coating. The minor changes in absorptance and emissivity after heat treatment in vacuum at 500 • C, together with high solar absorptance over a broad angular variation, establish the potential application of TiB 2 /Ti(B,N)/SiON/SiO 2 as a selective coating in concentrated solar power systems.

“…In recent years, much research interest has been devoted to the development of multilayer nanostructured coatings [1,2], in which high hardness is achieved and toughness is retained as a result of the dissipation of brittle fracture energy at grain boundaries and layer interfaces [3][4][5]. One possible architecture type of these coatings comprises alternating layers of nanocrystalline titanium nitride (nc-TiN) and amorphous silicon nitride (am-Si 3 N 4 ) [3].…”

Influence of ion energies on the structure, composition, and properties of multilayer Ti–Al–Si–N ion-plasma-deposited coatings

It is established that the energy of deposited particles influences the structure, composition, and properties of multilayer nitride coatings consisting of alternating layers of nanocrystalline TiN and amorphous Si 3 N 4 phases with inclusions of nanocrystalline hexagonal AlN formed at energies of titanium, aluminum, and silicon ions exceeding ~317 × 10 -19 , 267 × 10 -19 , and 230 × 10 -19 J, respectively. As the energy of titanium ions bombarding the substrate increases above ~512 × 10 -19 J, the phase transition from disordered TiN x to Ti 3 N 2 and the appearance of 2-to 3-nm-thick sublayers in 15-nm-thick nanocrystalline TiN x layers take place in the coating. The maximum hardness of such coatings reaches a level of ~54 GPa.
