A literature review of the main methods of modification and microalloying of deposited metal was made. It was shown that, in contrast to the term «microalloying», the term «modification» should consider not only a method of introducing small additives of chemical elements or their compounds into the deposited metal but also various physical effects or technological processes aimed at achieving the same goal – refinement of micro- and macrostructure of metal, cleaning of grain boundaries and boundary zones, improving the complex of technological, mechanical and operational properties of steels and alloys. Examples of such physical effects are application of vibrations to a product in the process of surfacing; input of power from a pulsed heat source; pulsed electrode or filler wire feed; application of sources with modulation of welding current; external electromagnetic effect, etc. The classification of modification methods depending on the scheme of their implementation and impact on the properties of the deposited metal is given. The main advantages and disadvantages of methods of introducing modifying and microalloying additives into the deposited metal are shown. It was determined that from the considered methods of modification, the chemical method is the simplest and the most rational, which implies introducing modifier elements into the deposited metal directly through the charge of flux-cored electrode wires. This method is technologically and economically simple and versatile, and can be used with minor changes in electric arc, electroslag and plasma surfacing. 33 Ref., 1 Tabl., 3 Fig.
