摘要
We study the influence of various functional (oxide, nitride, carbonitride, and carboxide) coatings with similar morphologies and sizes formed by the thermodiffusion saturation on the mechanical properties (short-term strength, plasticity, delayed fracture, and fatigue life) of VT1-0 commercially pure titanium. It is shown that, for the comparable morphologies of the surface layers, the phase-structural state of the coating exerts, in general, a noticeable influence on the mechanical properties of titanium under various loading conditions. At the same time, the minimum effect is produced by the two-component oxide coatings.
