The paper brings evaluation of selected materials regarding wear resistance under conditions of a chosen experiment. The following materials were selected for the experiment: steel C 45 in state after heat treatment and steel C 45 in state after quenching and tempering. The selected materials were compared to weld deposits C 508 and C 64 using three different techniques after being welded on and heat treated. The tribological experiment was performed on test device, which belongs to the category of pin-disk test devices. The resistance of the selected materials was evaluated regarding energy consumption in the process of wear and it was compared to with sizes of weight loss. It was observed that combination of materials C 508 + C 64 in the 1st group of samples and material C 508 in the 2nd one gave the best results. Regarding the energy consumption in the process of wear, the best results were obtained in basic material and in combination of materials C 508 + C 64 in state after hardening.
