Cast iron is one of the main structural materials, having a number of valuable service properties, in particular, wear resistance. Improvement of this characteristic is usually achieved by changing the structure of cast iron due to introduction of expensive alloying elements into its composition. The experiments carried out showed the possibility of transforming gray low-alloy cast iron to chilled wear-resistant one, due to modification of the deposited metal by small portions of tellurium powder. Electroslag surfacing was carried out in a current-carrying mold with melting of filler in the form of chips of low-alloy cast iron in the slag layer and additionally introducing flux-cored wire with a charge, containing tellurium powder, into the slag pool. 6 Ref., 9 Figures.
