Considered was efficiency of application of different schemes of additional alloying of deposited in arc process metal on change of its structure and hardness. The optimum parameters of the process and specific consumption of additional (alloying) materials with their preliminary fixing were determined. The highest indices of hardness of deposited metal are reached during local addition of TiC with fixation by GF-021 primer. 11 Ref., 1 tabl. 4 Fig.
