Wear resistance is one of the important functional properties in materials. In the present study, three different bulk hybrid nanomaterials were synthesized by using conventional high-pressure torsion (HPT) processing. The processed bulk hybrid metals were examined for evaluating the evolution of wear mechanisms and wear resistance. Tribological properties were investigated by using a reciprocal sliding tester for measuring the friction coefficient and wear properties which are tested through the worn scar analysis. The worn scar profiles were constructed by an optical interferometer and scanning electron microscope and the wear coefficient was calculated by the Archard equation. Together with additional supporting results from the hardness measurements and XRD analysis, there is a significant increase in the wear resistance in the bulk hybrid materials processed by HPT.
