The influence of modes of surface fusion by electric arc plasma (GTAW method) on the hardness and wear-resistance of plain cast iron was studied. A possible mechanism of structural rearrangement in the processed material during the friction was analyzed. This mechanism is determined by specific behaviour of hardened martensitic structure under dynamic load. This martensitic structure forms a metal basis of cementite eutectic under conditions of fast crystallisation.
