Дослідження трибологічних властивостей силікато-фулеренового геомодифікатора для поверхонь тертя

Abstract

Викладено результати лабораторних досліджень трибологічних властивостей захисного шару, утвореного силікато-фулереновим геомодифікатором. Встановлено, що використання геомодифікатора знижує коефіцієнт тертя у 2 рази. The reliability of the machines is largely determined by the friction and wearing processes. The reconditioning operation of the friction components without unmaking is a critical task that will significantly reduce both the repair costs and the agricultural machinery servicing costs. One of the ways of the reconditioning operation of the components without unmaking is using silicate-fullerene composition the production of which is now possible thanks to the advances of nanotechnologies.As a result of the laboratory researches the dependence of the friction coefficient on the duration of the experiment and the dependence of the temperature in the contact area on the load when using the silicate-fullerene modifier were determined.In the course of testing the friction coefficient greatly reduced and stabilized at 0.045 level that confirmed the formation of the covering layer on the working surfaces of the details. Using the silicate-fullerene geomodifier leads to reducing the friction coefficient 2 times.
