“…A number of additive materials such as titanium carbide (TiC), titanium nitride (TiN) and zirconium (Zr) are used to increase the fracture toughness and flexural strength of AlN‐based materials . These composites have been extensively studied for their possible applications in microelectronic devices, protective coatings for cutting tools, corrosion resistance, tribology and other mechanical devices .…”

Finite element modelling (FEM) is performed on AlN-TiN composites. The structure-property relationships are studied for 5 and 10 vol.% TiN composites in view of thermal and thermo-mechanical properties. Thermal stresses are simulated at various temperatures for the 5 and 10% TiN samples in homogeneous and heterogeneous temperature environments. It is found that compressive stresses are associated with the microstructure and these stresses are largest at the interface of the AlN-TiN phases. In addition, thermal strains are simulated at various temperatures for both the compositions. Thermal conductivity and thermal expansion coefficient are estimated using FEM and compared with other known analytical methods.

“…The dark spots seem to be due to surface relief. In [1, 5,6], it was convincingly shown, with reference to ESA of various materials with a composite of the TiN − AlN system, formation of a discontinuous heterophase electric-spark coating with uneven distribution of the phases over the surface. This is a result of impulse action of spark discharges on the surface under treatment, which causes dynamic distribution of temperature fields in the surface layer and concurrent occurrence of chemical processes and phase formation at various temperatures.…”

621.762The composition and structure of heterophase coatings on VK8 (WC − 8% Co) hard alloy cutting blades (inserts) were studied. The coatings were obtained by the methods of CVD of TiC with double magneticabrasive treatment and electric-spark alloying (ESA) with a TiCN − AlN-based composite as well as by combining these two methods. The wear resistance of WC − Co cutting blades with combination coatings was the best in tests on cutting the materials from SCh20 cast iron.

Results are provided for a study of the formation mechanism and conditions for high-temperature corrosion-resistant coatings, which are formed in air (>1500°C) with cyclic thermal changes under the action of concentrated energy sources. It is established that in composite materials of the systems (TiN-AlN)-(TiN-Cr 3 C 2 ) and (TiN-AlN)-(Ni-Cr)-(TiN-Cr 3 C 2 ) a complex oxide film forms that has good adhesion to a base and undergoes further composite oxidation, i.e., it promotes an increase in its scaling resistance.Development of contemporary technology is inseparably connected with a steady increase in working temperature, loading rates, and the effect of corrosive media. This provides a requirement for using fundamentally new materials, which guarantee reliability and the corresponding level of functional equipment properties. This relates mainly to ceramic and cermet composite materials based on oxygen-free refractory compounds (nitrides, carbides, borides). Among the multitude of ceramic materials there is considerable interest in composite materials of the systems TiN-AlN and TiN-Cr 3 C 2 , which exhibit a high level of tribotechnical [1], physicomechanical [2,3], and corrosion properties [4].Previously [5] the effect of concentrated solar radiation (CSR) on structure and phase transformations in ceramic composite materials has been studied for the systems TiN-AlN and TiN-AlN with a metal binder Ni-Cr-Al. It has been established that in these systems a dense oxide film forms consisting of two zones, each of which has a complex heterophase structure. The surface of the oxide film consists of Al 2 O 3 , TiO 2 oxides and NiCr 2 O 4 spinel, and the second layer of oxide film adjacent to the base is tialite b-Al 2 TiO 5 . This film exhibits high adhesion to the base and is a barrier preventing diffusion of oxygen into a specimen [5]. Action of CSR on a material is accompanied by occurrence of physicomechanical processes at its working surface, the same as rapid heating and cooling, the possibility of focussing energy in a small area, and also reaction of material components at high temperature.In order to increase corrosion resistance in air (>1500°C) and in corrosive media it is necessary to use either a coating, or a coating of more corrosion-resistant composites. For these coatings we have proposed composites of the system TiN-Cr 3 C 2 . In order to increase coating adhesion to a base a metal heat-resistant underlayer is used, i.e. Ni-Cr alloys, which wet well on one side to a ceramic TiN-AlN and on another to composite TiN-Cr 3 C 2 . These metal alloys exhibit high corrosion resistance and tribotechnical properties.The aim of this work is to study the mechanism and conditions of forming high-temperature corrosion-resistant coatings in air (>1500°C) with cyclic thermal changes under the action of concentrated streams of energy in order to explain coating oxidation under these conditions, and the possibility of increasing their resistance to high-temperature oxidation. The structure and structural phase transfo...
