    The effect of precipitation-hardening conditions on wear behaviours at 2024 aluminium wrought alloy
    (2003) Kaçar H.U.; Atik E.; Meriç C.
    In this study, wear behaviours of 2024 aluminium wrought alloy were investigated in different tribological conditions based on its ageing conditions. For this purpose, the alloy aged in five different temperatures and periods (at room temperature for 1 week, at 120°C for 24h, at 150°C for 18h, at 160°C for 16h, at 200°C for 2h) was worn in pin-on disc model wear test apparatus using different abrasive grit size (5, 11, 18 and 30μm SiC papers). Furthermore, the effects of different sliding speeds (0.078, 0.156, 0.208 and 0.338ms-1) and loads (6.45, 9, 9.3 and 11N) on wear resistance were also examined. It was measured amounts of mass loss and examined worn surfaces. The mass loss of the specimens increased with load and the abrasive grit size. © 2003 Published by Elsevier B.V.
