Abstract: In this article, the authors pay attention to the tribological behaviours of Al2O3 layers modified by tungsten disulfide powder. Oxide layers of Al2O3/WS2 were obtained by using hard anoding treatment in multicomponent electrolyte of sulphuric acid, oxalic acid and phthalic acid with 10, 20 and 30 g/l WS2 addition. PEEG/BG material was the tribological partner for the Al2O3/WS2 ceramics layer in reciprocating motion, under lubricant free friction conditions. Measurements were made with a T17 tribological tester. The results of the friction coefficient for the sliding couple and wear intensity of the PEEK/BG material are presented. The geometrical structures of the layers of Al2O3/WS2 surface before and after tribological interaction were measured using a Talysurf 3D Taylor Hobson profilograph. The obtained results indicate the following: - There is a possibility to improve the tribological properties of Al2O3 layers through the WS2 powder addition to the electrolyte. - Decreasing of the roughness of the counter-specimen after tribological interaction is the result of applied sliding film and also the amount WS2 powder that was put to the electrolyte.
