Abstract: It was established that comprehensive surface treatment of 12Cr18Ni10Ti (AISI 321) high-chromium stainless steel, combining the electro-explosive alloying with titanium and boron and subsequent irradiation with an intense pulsed electron beam, allows the formation of a multiphase submicro- nanocrystalline surface layer up to 60 µm thick, whose microhardness and wear resistance exceed the initial state microhardness by 7 times, wear resistance – by more than 9 times.

Keywords: plasma, intense pulsed electron beam, austenitic steel, titanium, electroexplosive boration, phase composition, defective substructure, properties.
