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.
