摘要：

Titanium-containing compounds soluble in mineral oils, such as titanium oleate and titanium 2-ethylhexanoate, as well as titanium dioxide nanoparticles modified by tetra(2-ethylhexyl)-thiuramdisulfide (TDS) and di(2-ethylhexyl)thiophonedisulfide (TFDS), were synthesized. Small-angle X-ray scattering was used to identify the structure of titanium carboxylates and determine the size of TiO2 nanoparticles. The antifriction and antiwear characteristics of these compounds were studied in various-type tribometers equipped with a four-ball friction unit. A comparative study of titanium-containing compounds with the highest tribological characteristics that contained nanoparticles modified by TDS and 2-ethylhexane acid at increasing velocity of sliding was carried out. The effect of titanium-containing compounds on the relief of worn surfaces was investigated.
