Abstract
! d, I% a3 A  G9 ]" b; NWear 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
