摘要

A complex method of the formation of diffusion strengthened layers of composites, according to which the soft matrix of the chromium solid solution in α‑iron relaxes the accumulation of internal stresses, and carbide inclusions (micrograins) of chromium allow us to resist high specific pressures under dynamic loads, is developed. The integral microhardness of the outer composite zone of the strengthened diffusion layer is 11–12 GPa, and service life reaches 107 cycles.
