Abstract
/ A. j# B% v$ V/ O5 E% T* o) cWear behaviour of age-hardened 6063 aluminium alloy was evaluated under dry sliding conditions. A certain part of the
( T1 D$ m& z8 h" x+ v% Saluminium 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

on a pin-on-disc machine showed that the aging treatments improved the wear behaviour of AA 6063 alloy compared to as-cast
samples.
