In the present paper, a model of wear mechanism of Al2O3/WS2 with polyether ether ketone (PEEK)/BG plastic has been presented. An amorphous Al2O3 oxide layer with a tungsten disulfide modifier has been characterized by the Scanning Electron Microscope equipped with an Energy Dispensive Spectrometer (SEM/EDS) and XRD analysis. The addition of WS2 to the acid bath reduces the friction coefficient of the Al2O3/WS2-PEEK/BG friction pair. The technology applied to receive the Al2O3/WS2 layer, with appropriately selected conditions, allows us to obtain a tribological layer that enables the delivery of WS2 solid lubricant during friction.
