Proceeding from published data, the influence of modification and microalloying by boron, titanium, tungsten, zirconium,
yttrium, etc., on the deposited metal structure, mechanical and service properties is shown. It is demonstrated that addition of
these elements or their compounds with carbon and nitrogen in the quantity of up to 0.2 %, allows producing a fine-grained,
homogeneous structure of metal, a more uniform distribution of alloying elements, that makes a positive effect on the values of
strength, ductility, wear and heat resistance. It was determined that, introducing small additives of boron or its compounds (in the
quantity of up to 0.2%), cerium or yttrium (in the quantity of up to 0.015 % of each), or application of complex master alloys,
which can have the above-mentioned elements in their composition, as well as such modifiers, as zirconium, titanium carbides
and borides or tungsten carbides, looks promising in terms of increase of wear and heat resistance of the deposited metal.
Proceeding from the performed analysis, it was also shown that addition of titanium and zirconium diborides to the composition
of flux-cored wire charge, promotes activation of the processes of formation of molten metal drops at the electrode wire tip,
resulting in improvement of the quality of metal transfer in the welding arc, that leads to greater values of the coefficients of
alloying element transition into the deposited metal and improves deposited bead formation. 28 Ref., 1 Tabl., 7 Fig.
