Abstract
& a+ y; e& `7 F. J" S8 R% ^" yWear behaviour of age-hardened 6063 aluminium alloy was evaluated under dry sliding conditions. A certain part of the
0 H6 ~1 J+ u4 a+ V$ D0 Xaluminium 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
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
' ~8 H9 S7 P; i' R1 H% uelectron microscopy (SEM), optical microscopy, X-ray diffraction, and energy dispersive detector (EDS). The wear tests using
! y. o4 A3 [1 ?+ m  c+ Ron a pin-on-disc machine showed that the aging treatments improved the wear behaviour of AA 6063 alloy compared to as-cast
samples.
