Metallographic studies of the microstructure of the experimental type of the deposited alloy of the Fe - C - Cr - Ni - Mn - Mo - Ti - Nb alloying system were performed. The chemical and granulometric composition of the metal-strengthening phases has been determined. The weld metal was tested for resistance to gas-abrasive wear at elevated temperatures. The wear resistance of the deposited metal was diagnosed by sclerometry with obtaining images of tracks from the indenter using atomic force microscopy. The character of microplastic deformation of worn surface layers of the alloy is investigated. The influence of the structural phase composition and hardening phases in the deposited metal on its wear resistance is discussed. Promising ways to further increase the resistance of the experimental alloy to gas-abrasive wear are determined.
