We have established the laws of formation of the structural-phase state, surface topography, and level of the near-surface strengthening of VT1-0, OT4, and VT6s titanium alloys at their thermodiffusion saturation from amorphous boron in nitrogen atmosphere. We have shown that high-gradient strengthened layers, formed due to contact saturation, especially in the temperature range from 900 to 950°C, exert a negative influence on the mechanical properties (plasticity, fatigue life) of alloys with such coatings.
