Water lubrication of PTFE composites

Abstract

Purpose

The paper aims to present results on the friction and the wear of polytetrafluoroethylene (PTFE) and eight commercially available composites with PTFE matrix, for tests done on shoe/roller tribotester with water lubrication in open circuit. There are pointed out particular tribological processes within the superficial layers of the composites with the help of optical microscopy.

Design/methodology/approach

Analysing the tribological behaviour of eight grades of PTFE composites sliding in water on shoe/roller tribotester.

Findings

Good results of wear behaviour under water lubrication for all the composites. PTFE exhibits severe wear under the tested regime.

Originality/value

The research could support PTFE composite application for water lubricated systems.
