Tribotechnical Characteristics of Commercially Pure Titanium with Different Grain Sizes and TiC and TiO2 Coatings

Resumo

The paper presents experimental data on the determination of the tribological properties of commercially pure titanium with different microstructures, with and without a coating. As a result of the performed experiments, it was established that the integral value of the friction coefficient, as well as its adhesive component, are structurally sensitive parameters. It is noted that the ultrafine-grained structure obtained as a result of severe plastic deformation contributes to a reduction in the friction coefficient, as well as to an increase in the load-bearing capacity of the triboconjugation.
