Abstract

The article presents a detailed study on the tribological performance of PTFE composites filled with iron–cobalt (FeCo) microparticles. It investigates the wear and friction behavior of these composites compared to those filled with Fe and Co microparticles. The research highlights the significant improvement in wear resistance achieved by the FeCo-filled PTFE, attributing it to the brittle nature of FeCo, which allows particles to break down and accumulate at the sliding interface, reinforcing the tribofilms. The study also provides insights into the tribochemical changes and the formation of transfer films, which contribute to the ultralow wear behavior. The article is rich in data, including particle size analysis, IR spectroscopy results, and wear rate calculations, making it a valuable resource for specialists in tribology and materials science.
