Abstract
; t, H: `' u9 o3 [, R; {$ R. QWear behaviour of age-hardened 6063 aluminium alloy was evaluated under dry sliding conditions. A certain part of the
aluminium samples was solution treated at 510 jC for 2, 4, 6 and 8 h, water-quenched then aged at 180 jC for 4 h, and the other

as-cast and the aged samples were fully characterised before and after the wear testing using hardness, profilometer, scanning
electron microscopy (SEM), optical microscopy, X-ray diffraction, and energy dispersive detector (EDS). The wear tests using
