Development of alloying fluxes for wear-resistant arc surfacing of rolling stock parts using mineral raw materials of the far eastern region

This work is intended for the development of new materials that ensure the required mechanical and operational properties and the quality of the surfaces formed. The paper presents the results of research into the development of fusion-ceramic welding fluxes for wear-resistant weld surfacing for the parts of the rolling stock. We have developed a methodology for obtaining such fluxes and conducted theoretical calculations and experimental research. The latter resulted in obtaining fluxes (granodiorite - 5.8 %, fluorite - 3.7 %, marble - 4.1 %, zirconium concentrate - 4.9 %, ferromanganese - 19.6 %, titanium- magnetite - 3.7 %, braunite - 1.2 %, scheelite - 2.1 %, graphite - 5.5 %, ferrochrome - 28.9 %, and АN 22 or АN 348А - 20.6 %). The required properties are achieved through the reduction of alloying elements and the formation of chrome carbide (Cr7C 3), iron-carbide (Fe3C) and other substances in the deposited weld layer.
