Résumé : 

The dry tribological behavior copper-graphite and graphite-graphite pairs in sliding contact is studied. The tests were carried out with a pin-on-disc tribometer in ambient air. The experimental results show the evolution of the temperature as a function of the normal load and the sliding speed. These results show that these two parameters have a significant influence on the variation of the average contact temperature. The discussion of results is based on observations by optical microscope and interfacial phenomena resulting from friction
