“…We sprayed Ti-TiO 2 composite coatings as robotic complex for detonation spraying (IntelMashin LLC) equipped with a multi-chamber detonation accelerator. 31,32 The barrel was moved during the process of spraying the powder composition using a vertical sweep. We sprayed Ti powder on the steel samples at two different distances between nozzle and substrate (spray distance): 40 mm, (sample code is St/4) and 50 mm, (sample code is St/5) and on the plastic samples at 100 mm.…”

The influence of UV irradiation intensity on the rate constant of photocatalytic reaction of TiO2 coatings applied by detonation spraying on the hot‐rolled carbon steel and glass‐cloth‐base laminate (plastic) is studied. The effect of substrate material on the studied phenomenon is pronounced. The kinetic curves at different UV irradiation intensities and the rate constants of the photocatalytic reaction are obtained for different values of energy flux density varied from 3.0 to 8.0 mW/m2. The photocatalytic rate constant of coatings placed on plastic increases with an increase in the energy flux density from.038 to.055 1/h. Samples applied at a spray distance of 50 mm are characterized by a higher the photocatalytic rate constant than those applied at a distance of 40 mm. The value of photocatalytic rate constant does not change starting from a certain flow value for such samples and reaches the saturation value of about.054 1/h. Saturation is achieved quite quickly already at a density flux of about 5.5 mW/m2. Two new phenomenological models based on differential equation, the analytical solutions to which sufficiently describe experimental dependence of the photocatalytic rate constant on the energy flux density, are proposed.

The article studied the effect of annealing on the structure and properties of zirconium dioxide coatings obtained by detonation spraying. Detonation spraying was realized on a computerized detonation spraying complex of the new generation CCDS2000. Determined that coatings made of zirconium dioxide are characterized by high adhesive strength of adherence to the substrate. Thermal annealing of coated samples was performed at temperatures of 900-1200◦ C. It was determined that the microhardness of zirconium dioxide coatings increases by 10-25% depending on the annealing temperature after annealing. The results of nanoindentation showed that the nanohardness of the coatings after annealing at 1000◦ C increases by 50%. It was determined that after annealing at 1000◦ C, the elastic modulus of the coatings increases, which indicates a decrease in plasticity and an increase in the strength of the coatings. X-ray diffraction analysis showed that the phase composition of coatings before and after annealing consists of t-ZrO2. After annealing occurs there is an increase in the degree of t-ZrO2 tetragonality. Electron microscopic analysis showed that an increase in the number and size of micro-continuity in the form of thin layers after annealing. Determined that increase the hardness of zirconium dioxide after annealing at 900-1200◦ C is associated with a higher degree of tetragonality t-ZrO2 phase.

“…A series of studies conducted by our group were focused on the formation mechanisms, microstructure and properties of coatings obtained from HEBM powders by cold spraying (CS) [57][58][59] and detonation spraying (DS) [57,[60][61][62][63][64][65][66][67][68]. The purpose of HEBM was to produce composite particles suitable for spraying or to form an alloy from the starting metallic components.…”

High-energy ball milling (HEBM) of powders is a complex process involving mixing, morphology changes, generation and evolution of defects of the crystalline lattice, and formation of new phases. This review is dedicated to the memory of our colleague, Prof. Michail A. Korchagin (1946–2021), and aims to highlight his works on the synthesis of materials by self-propagating high-temperature synthesis (SHS) and thermal explosion (TE) in HEBM mixtures as important contributions to the development of powder technology. We review results obtained by our group, including those obtained in collaboration with other researchers. We show the applicability of the HEBM mixtures for the synthesis of powder products and the fabrication of bulk materials and coatings. HEBM influences the parameters of synthesis as well as the structure, phase composition, phase distribution (in composites), and grain size of the products. The microstructural features of the products of synthesis conducted using the HEBM precursors are dramatically different from those of the products formed from non-milled mixtures. HEBM powders are also suitable as feedstock materials for depositing coatings by thermal spraying. The emerging applications of HEBM powders and future research directions in this area are discussed.
