“…-Low degree of oxidation in the transmission process; ESD and AFS are accompanied by rapid specific chemical-thermal phenomena, occurring at high local temperatures and pressures. These conditions require the laminating material to be less susceptible to high-temperature oxidation processes or to use self-lubricating additives in order for to prevent the formation of oxide and nitride phases, which cause brittleness of the applied layer, [1][2][3]10,11,25,[27][28][29][30].…”

“…The wrong choice of material for the application of wear-resistant coatings does not allow obtaining a satisfactory combination of the required level of performance characteristics of tribosystems with acceptable process ability, maintainability and cost-effectiveness of the processes of manufacturing and repairing parts. Numerous and various data are available in the literature on studying of the structure, composition and properties of wearresistant coatings applied by both methods [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] and many others. There the basic principles of the formation of the coating are given, and numerous data on their properties, the nature, and type of wear and tear in different conditions, and the results of their application taking into account the 1.3 to 10 and more times the increase in durability.…”

The aim of the present work is to identify and formulate the basic principles and approaches for the selection of materials for electrical spark and gas-flame stratification of structural steels. For this purpose, have been examined: -The characteristic features and physical foundations of the two methods, the changes in the composition and structure of the coating materials in the transfer process and in the formation of the coatings and the general similarities and differences.-The regularities of formation and qualitative characteristics and properties of the coatings obtained, depending on the process parameters of the coating mode and the layering material.-The interrelation between: the process parameters of the application system; the coating material; the quality characteristics, the composition, the structure of the coatings; the mechanical and the tribological properties of the coatings. The requirements for coatings have been formulated for various loads and wear cases and on this basis the requirements for the layering materials are determined by the two methods. Appropriate materials and compositions are specified for various cases of friction and wear. The main approaches to the selection of the layering materials are described.

“…Gas Flame Spraying (GFS) [4,5,6,7,8] and Electrical spark deposition (ESD) [9][10][11][12] are of the most versatile, lightweight and affordable methods for applying wear-resistant coatings. Both methods are realized by converting the layering material into molten particles, which are applied at high speed to the surface of the coated article and bonded thereto.…”

In this work are presented the results of comparative tests of the abrasion wear characteristics and the wear resistance of new coatings from multi-component composite materials. The main objective of the study is to reveal the mechanisms of wear and optimization of the composition of multi-component materials to obtain high wear resistant coatings under conditions of abrasion and erosion. The coatings are applied by electrical spark deposition and gas-fuel spraying on carbon steel substrates. Composite mixtures of Cr-Ni-Co-B-Si-C, reinforced with micro-sized particles of boron and tungsten carbides, and titanium diboride in varying proportions are used for layering. Results were obtained for the influence of microgeometric parameters, the composition and microstructure of coatings on their wear resistance and on the characteristics of the wear at different loads under dry abrasive friction. It has been found that the resulting coatings have a 20-50% higher wear resistance than the conventional materials used. The compositions of layering materials and the process parameters of the two methods have been determined, at which maximum wear resistance of the coated samples is obtained.
