Abstract
In this paper the tribological behaviour and wear resistance of composite coatings based on zinc with PTFE (polytetrafluoroethylene) particles are investigated. The coating types included in this paper cover a broad range of coatings composition, deposition conditions, and measurements. Characterisation and understanding of tribological behaviour requires the exact definition of the coatings’ composition, PTFE content and distribution in the composite coatings. A number of analytical methods were used to characterise all required parameters, e.g.friction coefficient measurement, optical microscopy, infrared spectroscopy, etc. Each method proves better or worse ability to describe tested coating. Test results show, that incorporation of PTFE particles into zinc coating positively effects friction coefficient, self-lubrication, etc. It is obvious that these effects changealong with the particles content.© 2011 Published by Elsevier Ltd.
