There was investigated process parameters (bulk density and compactability at different pressures) of ready-to-press (RTP) powders of hard alloy WN8 (WC + 8 % Ni) with different binders, in conjunction with achievable green macrostructure, in the first place, absence of post-pressing cracks and large inter-granular porosity (> 60 μm), that was specified by means of mercury porosimetry and scanning electronic microscopy methods. RTP powders were prepared with using of conventional technology that is mixing with binder solution, drying and consequent rubbing through grate, with aid of different industrial binders on the base of synthetic rubber, paraffin wax, polyethylene glycol, and water-soluble binder. Debinding temperature ran- ges were determined by means of thermogravimetry method. There were showed advantages and disadvantages of studied binders. 

There were presented results of analysis regard to influence of duty parameters of ejection nozzle on characteristics of highly dispersed powder of alu- minum under the conditions of production of enterprise LLC «SUAL-PM». There were conducted measurements of dispersed indices of spray product under condition of aluminum melt spraying by ejection nozzle at various flow rate and temperature of atomizing gas, consequently, at the range of 0,17–0,21 m3/s and 873–933 K, as well as temperature of melt in the range of 1153–1253 K. There were presented results of medium particle diame- ter determination (dm) and content of highly dispersed fraction (z) (with particles diameter ≤ 10 μm) in spray product. There was showed that under modification of duty parameters of nozzle value of dm is decreasing by 3,7–12,4 %, and value of z is increasing by 0,4–3,2 %. There was established that most effective factor influencing on powder properties, is increasing of temperature of atomizing gas. 

There was considered influence of nanosized carbon additives on structural phase state and properties of the sintered alloys on the copper, iron and tungsten-cobalt base. There was demonstrated that under liquid phase sintering and crystallization process of powder compositions that contain nanosized carbon particles. non-dissolved fraction of nanosized additive could be stands as additional nucleation centers, that promotes atomization of structure. There was established that for alloys that could be form solid solutions with carbon or hardening carbide phases. nanosized diamond- graphite additives increase of hardness of sintered composites and improve its tribotechnical characteristics 

The work was devoted to investigation of kinetics of SHS-process, staging of chemical transformations and structure formation of ceramic materials in multicomponent Cr–Al–Si–B system. An influence of reactionary mixture composition and initial temperature of the SHS-process on the combustion tem- perature and rate was investigated. The values of that parameters decreases during increasing of Al concentration. Increasing of the initial temperature of SHS-process leads to directly proportional growth of said indices, suggesting the single combustion mechanism for each composition, when staging of chemical reaction of synthesis products formation is not change. Besides, increase of Al content leads to increase of portion of Al–Si eutectic melt, and dissolving of Cr particles in this melt becomes a limiting stage of the combustion process, which leads to decrease of effective activation energy values from 291 to 109 kJ/mole. The staging of chemical transformations in the combustion wave was investigated and an assumption about mechanism of struc- ture formation was made. Initially, in the preheating zone a contact melting of Al–Si eutectic occurs with subsequent formation of the reactionary sur- face by spreading of the melt on the surface of Cr and B particles. Then the melt is saturated with these elementss with further crystallization of CrB and Cr(Si,Al)2 grains. In the areas enriched by Cr and B and depleted by melt the formation of CrB may occur by a mechanism of solid-phase interaction invol- ving gas-transport reactions. Sequenced formation of monoboride CrB, and then silicide Cr5Si3 or alumosilicide of Cr Cr(Si,Al)2 was established by means of dynamic diffraction method. Ceramic targets for magnetron deposition of multicomponent coatings were produced by forced SHS pressing technology. 

There was investigated influence of titanium carbonitride TiC0,5N0,5 doping by transition metals IV–VI groups on mechanism of contact interaction with nickel melt. There was established that said doping deep destabilizing influence, simultaneously increasing as velocity of dissolving in nickel both de- gree of process incongruence (preferred transition in melt of alloying metal and carbon). Influence of alloying metal on phase stability of carbonitride TiC0,5N0,5 in contact with nickel melt is demonstrate in its dehomogenization or phase segregation. Destabilizing effect of alloying additives is increa- sing in the range of MeIV–MeV–MeVI in parallel with decreasing of its affinity to nitrogen. 

There was investigated influence of long-term high temperature annealing on structure and phase composition of diffusion zone in copper-titanium composite, receiving by means of explosion welding and subsequent rolling. 

In consequence of mechanical processing of powder PAP-2 during 15–180 min were attained its pelletizing and increase of its bulk density: γc = 0,4÷1,0 g/cm3, in the state of free loading, γу = 0,75÷1,25 g/cm3, after ramming. By means of X-ray diffraction analysis in grains structure was de- tected a few components of Al, that differenced by crystal lattice parameter (α0 = 0,40474÷0,40636 nm), that was result from lattice distortion owing strike impact of hard alloy milling agents. There was determined crystal phase θ–Al2O3 (2 %). Physical and mechanical properties of ceramet Al-Al2O3, receiving by reaction sintering in mode of filtration burning of pressings, manufactured from granulating powder PAP-2, were following: density – 2,3÷2,5 g/cm3, bending strength – 170÷250 MPa, axial and diametral compression strength – 200÷300 and 70÷100 MPa, correspondingly, buckling strength – (4,3÷7,0) ∙ 103 J/m2, relative strain to fracture at axial and diametral compression – 6,6÷10,8 and 6,2÷7,5 %. 

This article is continuation of authors’ publication cycle on subject «Multifunctional protective c-e for extra heat-stressed elements of structure of hypersonic systems». There was made analysis of modern domestic approaches to creation of single-ply and multilayer protective coatings of various classes: glass-ceramic, receiving by means of different methods; on the base of oxide ceramics; oxygen-free reaction-bonded; microcomposite syner- getic type. There was paid attention on full absence of applied science investigations, oriented on development of structured and physic-chemical models of coatings’ architecture, substantiation it’s functioning in the conditions of interaction with gas’ high-speed flow. Selection of coatings’ chemical composition and processing technology of its formation is realized basically on empirical base. There was presented a range of coatings, declared as workable in the still or weak perturbed air up to temperature 1600–2000 °C; however, there is not realistic estimate its protective capabilities in the conditions of impact of high entalpic ultra- and hypersonic oxygenated gas flow, owing lack or absence of appropriate data. Especially pinpointed microcomposite coatings of synergetic type Si–TiSi2–MoSi2–B–Y, developed in the frame of original conceptual approach to creation of multilevel sys- tem of heat protection of heat-stressed construction elements from heat-resisting materials of hypersonic motor apparatus and its propulsion plants. Detailed analysis of its r within single constructive wall with protected carbonaceous material allows detect trends and directions of authors’ follow- up study with the aim of development’s improvement.
