Abstrakt:	It has been established that heating of a low-carbon deposited metal containing ~5, ~8 % Mn and additionally ~3% Cr having a martensitic structure to an intercritical temperature interval (ITI) provides a secondary metastable austenite, which undergoes a dynamic deformation martensitic transformation (self-hardening effect under loading). This significantly increases the wear resistance at dry sliding friction and impact abrasive action of the shot stream. The deposited metal with a higher manganese content (~14%) yield to the wear resistance under conditions of dry sliding friction of a metal containing 5% and 8% of manganese, but has a higher wear resistance than it when subjected to impact-abrasive action of the shot stream.
