This paper presents an experimental study of the tribological behavior of a sliding contact pin-disc. This study concerns a brass-steel dry dynamic contact where friction and wear are studied in terms of mechanical parameters, without passage of electric current. To release this study, a tribometer, pin brass rubbing against a rotating steel disc is used in an atmospheric ambiance. The testing parameters are: the normal load (5-30 N) and sliding velocity (0.1-0.5 m/s). The duration of each test is 30 min. Experimental results show that these parameters have a significant effect on the tribological behavior of the studied couple. The discussion of results is based on observations, using a profilometer, worn surfaces and interfacial phenomena resulting from the sliding contact process.
