| Popis: | The development of new types of high-pressure plastic lubricants using natural minerals is of much importance. The effects of surfactant proportion and the structure of the nanoparticle thickener surface on the tribological properties of the bentonite-based grease were studied. The plastic lubricants that provide the best anti-friction and anti-wear properties were revealed to be the one that is modified by quaternary amine and urotropine-type ammonium salts. The surface ratio of bentonite particles modified by quaternary ammonium salts, which results in composite with the best tribological properties, was also revealed. |
