Use of Epoxy Fluoroplastic Coatings in Friction Pendulum Bearings

Abstract:

In this paper, we consider the possibility of using, in friction pendulum bearings, multilayer friction proof coatings based on polytetrafluoroethylene compounds modified by nanoscale spinels such as magnesium, zinc and chromium. The tribological effect of applying the coating is achieved by formation of a friction transfer layer. For better wear resistance, we applied a multilayer coating with a power frame covered using electrospark coating. We performed an experimental research of bushing samples and various coating fluoroplastic bases. The research on a friction machine “SMT-1” has shown the effectiveness of epoxy fluoroplastic composition as an anti-friction coating in comparison to other types of fluoropolymer bases.
