“…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.

“…It should be noted that since the creation of the first installations, the principle of their operation has not undergone significant changes, which cannot be said about some components of the spraying apparatus itself (nozzles, powder dispenser, etc.) [9,10]. The automation of the process has improved largely: the elimination of the human factor, due to the introduction of software, improving the accuracy of surfacing, due to the improvement of individual parts of the installation and optimization of the deposition processes.…”

In this work, consider the aspects of obtaining powder coatings that possessing certain working properties obtained by detonation spraying. Experimental research were carried on the effect of technological parameters of the detonation spraying process on the phase composition and properties of Ti-Si-C coatings. It is determined that when the volume of filling the detonation barrel with an explosive mixture increases to 70% in the detonation wave flow, the Ti 3 SiC 2 powder partially decomposes into TiC consequently the high-speed shock interaction of heated to high temperatures. Installed that when filling the barrel with an explosive mixture of 50% and 60%, a low extent of decomposition of Ti 3 SiC 2 powder can be achieved. It is determined that an increase in the volume content of the TiC phase in the composition of coatings bring to a decrease in the hardness of the TiC -Si coating.

“…%) was introduced into the mixture of O 2 + C 2 H 2 (reprinted from [29], Copyright (2015), with permission from Elsevier). The characteristic feature of coatings produced from Ti 3 Al was the presence of titanium nitrides Ti 2 N and TiN with relative contents changing with increasing explosive charge or oxygen content in the acetylene-oxygen mixtures [30,47]. The source of nitrogen in the detonation sprayed coatings was air or nitrogen used as carrier gases while the exact phase composition of the coatings was affected by the particle temperature.…”

This article is a focused review aimed to describe the potential of the computer-controlled detonation spraying (CCDS) for producing and designing coatings with variable chemical and phase compositions and microstructure and promising properties. The development of the detonation spraying method is briefly analyzed from a historical perspective and the capabilities of the state-of-the art facilities are presented. A key advantage of the CCDS is the possibility of using precisely measured quantities of the explosive gaseous mixtures for each shot of the detonation gun and different oxygen to fuel ratios, which can create spraying environments of different chemical properties—from severely oxidizing to highly reducing. The significance of careful adjustment of the spraying parameters is shown using material systems that are chemically sensitive to the composition of the spraying environment and temperature. Research performed by the authors on CCDS of different materials—metals, ceramics, intermetallics and metal-ceramic composites is reviewed. Novel applications of detonation spraying using the CCDS technology are described.
