摘要：
Special features of structure formation in the heat-affected zone of roll-foundry iron with flaked or globular graphite due to surface heat treatment by direct electric (plasma) arc are considered. The influence of the parameters of the process on the composition, structure, and properties of the hardened zone is studied. Treatment modes ensuring a structure with enhanced hardness and wear resistance in the surface layer of iron are determined.
