Аннотация

The work is aimed at detection and analysis of the formation regularities of phase composition, defective substructure, mechanical (microhardness) and tribological (wear parameter and friction coefficient) properties of high-chromium austenitic stainless steel of AISI 304 grade, subjected to borating in the scheme of plasma-assisted RF-sputtering of boron cathode. The formation of multiphase multi-layer hierarchically organized structure in the surface layer with thickness up to 40 ȝm is revealed. It is characterized by high wear resistance, which exceeds that of initial steel by more than 100 times. It is shown that the main mechanisms of strengthening the modified layer are solid solution strengthening, due to saturation of iron crystal lattice with boron, and dispersion strengthening, connected with extraction of nanosized particles of boride phase.
