Description	Zinc coatings with dispersed polytetrafluorethylene particles (Zn-PTFE composite coatings) were produced by zinc electrolytic plating in weakly acid bath in semi-industrial scale. The technology was built on the results of the series of laboratory experiments which enabled us to determine an optimal setting of process conditions. Those conditions had significant effect on the incorporation of PTFE particles into zinc matrix and, consequently, on the friction and corrosion properties of Zn-PTFE coatings. The composition of Zn PTFE coatings was analyzed by microscopic analysis and infrared spectroscopy and the properties of the coatings were studied by tribological experiments and corrosion tests. The results confirmed the positive effect of PTFE on friction properties of Zn-PTFE coatings and showed that the corrosion resistance of Zn PTFE coatings was similar to Zn coatings without PTFE. The application of such coatings is suggested for the production of bolt joints, pins, bearings, and components with threads, i.e. any moving and rolling components of chassis, landing gears or engines used in automotive or aircraft structures.
