Adhesive and tribological properties of fluoroplastic materials in contact with different metal surfaces

The paper examines the effect of ambient temperature, pressure, and nature, treatment purity, and oxidation of different metals on the tear strength of metal–fluoroplastic (pure and reinforced) surfaces. It is established that both pure and reinforced fluoroplastic shows strong adhesion to different metal surfaces at temperatures higher than the melting temperature of fluoroplastic and close to its sintering temperature. Fluoroplastic materials have lower wear resistance at high sliding speeds when high temperature is generated in the friction area since adhesion of fluoroplastic to the counterface surface substantially increases.
