Abstract
The paper considers the possibility of tribological application of epoxy composites filled with microcapsules with a lubricant. Microcapsules in polyester shells containing industrial oil I-40 were added to the matrix of epoxy-diane resin ED-20.
During slip tests, the capsules are damaged by counterbody irregularities, causing oil to enter the contact area. The lubricating effect of the released oil and the trapping of wear particles in the cavities left by the ruptured capsules lead to a significant reduction in both the coefficient of friction and the specific wear rate.
An important role in ensuring the performance of the friction unit is played by tribochemical reactions that occur during the interaction of the composite with the metal surface. The kinetics of the formation of secondary surface structures during friction was studied by attenuated total internal reflection IR spectroscopy. The morphology and elemental composition of the structures formed on the surface of the counterbody during friction were studied using a Zeiss EVO MA 18 scanning (raster) electron microscope (SEM) equipped with an X-Max 50N energy dispersive analyzer (EDS).
