The contribution brings the evaluation of selected materials regarding wear resistance under conditions of two experiments. The following materials had been chosen for these experiments: steel E295, steel C 45 after heat treatment, steel C 45 after quenching and steel 16MnCr5 after carburizing and quenching. The experiment was performed on a test device belonging to the category of “pin – disk“ test devices. The resistance of selected materials was evaluated regarding energy consumption, and it was compared to sizes of weight loss. It was observed that the material C 45 after heat treatment reached the highest values of wear resistance in conditions of adhesive wear without lubrication. The material 16MnCr5 indicated the best results in conditions of abrasive wear.
