“…In addition, the wear of individual parts leads to a gradual decrease in performance, efficiency and work parameters of a machines and complexes. Considering into account the constantly growing requirements, it is necessary to increase the efficiency and effectiveness of technological processes, machines and vehicles [ 2 ]. The theoretical foundations of healing crack-like defects in structures using repair coatings and patches were developed for cracked plates [ [3] , [4] , [5] ] and shells [ [6] , [7] , [8] , [9] ].…”

“…The cost of worn parts in mining is approximately the same as the cost of maintenance. In addition, wearing of some equipment in mining industry can lead to catastrophic failures and emergency stops, which can have a bad influence to equipment efficiency [11]. Since the greatest number of industrial parts is withdrawn from exploitation due to wear (53% abrasive, 24% adhesive, 10% impact and other kinds of wear) and corrosion (13%) [12].…”

“…Among the whole variety of applied exothermic addition systems, the exothermic addition CuO-Al system is of a great interest, because it allows to perform additional alloying of deposited metal by copper [29]. The positive effect of alloying with copper deposited metal can be an increase in corrosion resistance [11].…”

In this research, the mechanical and tribological properties of two deposited metal of Fe-C-Cr-B-Ti alloying systems. In this study, comparative tests of the deposited metal hardfacing by two self-shielded flux-cored wires electrode were carried out: with an exothermic additive (110Cr4Cu5Ti1MnVB) and without an exothermic additive (140Cr15TiSi1MnVB). Abrasive wear resistance was evaluated using a slightly modified procedure on a standardized tribological machine for abrasive wear, according to the limits established by the ASTM G65. The results of studies of the efficiency of introduction of an exothermic addition CuO-Al system into the core filler of a flux-cored wire electrode were presented.

The spontaneous infiltration method for fabricating composites was used, in which molten Cu–Ni–Mn–Fe binders penetrated W–C filler particles due to capillary forces. The metal matrix composites thus obtained were characterized for phase composition, microstructure, porosity and microhardness. All composites were studied in their as-prepared condition with further annealing at 900°С for 60 and 750 h. It was shown that the mechanism based on the dissolution/diffusion bonding of the particulate/matrix interface was in agreement with the results of this study. The interfacial reactions provided a driving force for wetting but did not give rise to unwanted phases that could degrade the properties of the composite materials. From the EDX measurements it was concluded that mainly Fe atoms diffused from the Cu–Ni–Mn–Fe binders into the WC phase of the eutectic (WC+W2C) filler. Dissolution of this phase resulted in the appearance of W2C layer at the interface. Annealing at 900°С significantly promoted the interfacial reaction especially during the first 60 h of heat treatment. The degree of the reaction between the molten Cu–Ni–Mn–Fe alloys and W–C particulate could be limited by controlling the iron content of the binders to obtain an optimal interface.
