Abstract In this study, wear mechanisms of Al6061-CNT nanocomposites produced by cryomilling and mechanical milling, cold compacting and extrusion have been studied. The wear maps showed that the maximum amount of abrasive wear region in all milling times, was observed for the cryomilling samples. Also these maps show that the abrasive wear region for the cryomilling and mechanical milling was maximized at 12 h milling time. For cryomilled samples with 8 h milling time or more, the weight loss decreases with increasing sliding speed at normal loads of 5 and 10 N, also abrasive wear mechanism was observed at above conditions. Cryomilled samples show increased resistance against delamination and crack initiation during wear test.
