The study is devoted to solving the problems of abrasive wear of mining equipment parts operating in harsh Arctic conditions. The effectiveness of surfacing with direct current and modulated current was compared. It was found that the use of pulsed-arc technology reduces the burn-off of alloying elements in the melt. This ensures better transfer of the electrode's chemical composition to the surfacing layer and targeted adjustment of its properties. The results showed that the influence of the technology on the coating hardness varies depending on the composition of the surfacing material, confirming its potential for managing the quality of restoration of critical components.
