Abstract: The paper presents the results of a study of the influence of biological lubricants on the tribological properties of the friction pair "steel - titanium alloy". Tribological tests were carried out with indentation (scratching) on a friction path of 2 mm with an increase in load from 0.030 to 10 N on a Micro Indentation Tester CSM. The studies were carried out under various conditions: dry rubbing, with hyaluronic acid and with biological oil. It was found that lubricating media of biological origin create boundary lubricating layers on friction surfaces and are able to reduce wear due to microcutting. The development and experimental verification of a mathematical model expressing the dependence of the penetration depth on the friction path and other parameters has been implemented.

Keywords: biological lubricating media, titanium alloy, high-temperature deformation, tribological properties.
