Tribological behaviour of the self-lubricating polymers against steel 45 using different velocity

Resumo

Tribological investigations of polymers and polymers with additives, using the SMC-2 device, were showed in the present work. Friction coefficient and contact temperature of sliding friction couples, containing different basic materials (PA66 and POM, with two types of nanoparticles, with five different concentrations 0; 0.5; 3; 7.5 and 15% by volume) were investigated. Self-lubricating polymers and steel friction couples have been tested without any lubrication. Research has shown, that the concentration of copper and graphite nanoparticles exceeding 5% leads to coagulation part, that reduces frictional properties of the base material.
