Effect of inducing the external magnetic field in arc surfacing over preliminary deposited alloying charge (carbon-containing fibers + SiO2
) on hardness and structure of metal, as well as on change in the above-mentioned indices within the limits of single beads was investigated. It was found that the carbon-containing fibers applied to the part surface being deposited cause during surfacing the local enrichment with carbon of a liquid phase, which is decayed in cooling for ferrite-carbide mixture, that leads to the increase in metal hardness. Additional inducing the external magnetic field in process of surfacing promotes intensive stirring of weld pool that results in producing the more uniform structure and hardness. The analytical dependencies of hardness of deposited layers on amount of carbon-containing fibers, SiO2
+ Fe and magnetic field induction were obtained. The results of investigations can be used in development of technology for manufacture and restoration of parts operated under the abrasive wear conditions. 9 Ref., 1 Table, 10 Figures.
