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.

“…In addition to experimental methods for the development of materials for wear-resistant coatings, the results of thermodynamic modeling [ 77 , 78 ], the calculation of crystal lattice properties [ 79 , 80 , 81 ], the determination of factors influencing corrosion resistance [ 82 ], and a rational choice of deposition process parameters [ 83 , 84 ] are very important for achieving the maximum result of surface reinforcement. When developing technological processes for depositing coatings [ 85 ] and modeling metal melting processes [ 86 ], it is also necessary to take into account the influence of external factors, as well as to apply intelligent methods for comparing energy processes [ 87 ].…”

An analysis of common reinforcement methods of machine parts and theoretical bases for the selection of their chemical composition were carried out. Prospects for using flux-cored arc welding (FCAW) to restore and increase the wear resistance of machine parts in industries such as metallurgy, agricultural, wood processing, and oil industry were presented. It is noted that conventional series electrodes made of tungsten carbide are expensive, which limits their widespread use in some industries. The scope of this work includes the development of the chemical composition of tungsten-free hardfacing alloys based on the Fe-Mo-B-C system and hardfacing technology and the investigation of the microstructure and the mechanical properties of the developed hardfacing alloys. The composition of the hardfacing alloys was developed by extending the Fe-Mo-B-C system with Ti and Mn. The determination of wear resistance under abrasion and impact-abrasion wear test conditions and the hardness measurement by means of indentation and SEM analysis of the microstructures was completed. The results obtained show that the use of pure metal powders as starting components for electrodes based on the Fe-Mo-B-C system leads to the formation of a wear-resistant phase Fe(Mo,B)2 during FCAW. The addition of Ti and Mn results in a significant increase in abrasion and impact-abrasion wear resistance by 1.2 and 1.3 times, respectively.
