The parameters of nitriding of technically pure titanium VT1-0 are recommended for obtaining regulated surface-to-surface reinforcement. The nitrogenation of the endoprostheses of the hip joint equipment is developed and adapted to reproduce the technological regulation of thermodiffusion saturation with nitrogen, providing temperature-time and gas-dynamic treatment.
