Considered was efficiency of use of different schemes of preliminary application of alloying powders on structure and hardness of metal deposited by arc method. 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 its fixation by GF-021 primer. 11 Ref., 1 Tables, 4 Figures.
