Abstract

The hybrid coatings prepared on aluminum substrates were the object of a study of their tribological properties. An amorphous oxide layers Al2O3 were obtained on aluminum alloy EN AW 5251. The top coatings were sol-gel matrices with embedded nanoparticles of inorganic fullerene-like tungsten disulfide IFWS2. The coatings were coupled with two kinds of plastic TG15 and PEEK/BG in order to measure their tribological properties as wear intensity and friction coefficient. Scanning electron microscope and surface adhesion were also studied.

Keywords: Composite coatings, sol-gel method, inorganic fullerene-like tungsten disulfide, tribological properties
