The Tribological Properties of ZN-PTFE Composite Coating

This study deals with new composite electroplated Zn-PTFE coating, it is focused on description of composite coatings in elecrtoplating, especially on Zn-PTFE composite coatings. Zn-PTFE coatings are electroplated Zinc coatings added by PTFE particles. This article describes testing of tribological qualities of Zn-PTFE coatings in comparison to Zinc coaating or surface without any surface treatment. Results introduce connection between technological parameters of electroplating and tribological propetries. Tribological tests were realized by using TOP3 tribometer, placed in laboratories of Department of Manufacturing Technology, Faculty of Mechnaical Engeneering, CTU in Prague.
