Abstract
5 x  O; J! z8 O6 x4 _% u3 D$ a' YWear behaviour of age-hardened 6063 aluminium alloy was evaluated under dry sliding conditions. A certain part of the

part was solution treated at 510 jC for 6 h, water-quenched then aged at 180 jC for 1, 2, 3, 4 and 5 h in a muffle furnace. The
as-cast and the aged samples were fully characterised before and after the wear testing using hardness, profilometer, scanning
