abstract The presented work is a continuation of tribological research on alumina/graphene composites. In our previous publication the results of wear tests on the above mentioned composite at room temperature, but also at temperatures of 150, 300 and 500°C were presented. The studies showed that this composite is promising in relation to pure alumina at ambient temperature and 150°C. In order to determine more precisely the temperatures at which the tested material can work, abrasion tests were carried out at two additional temperatures, 80 and 200°C, and the results are presented in the following paper. Noticeable plastic deformation and wear greater than at room temperature was detected already at 80°C but it was still significantly lower than at 150°C when the composite wore significantly less than pure alumina. The test carried out in 200°C gave results similar to those for 300°C, which indicates significant degradation of the material at this temperature.
