Abstract
Wear behaviour of age-hardened 6063 aluminium alloy was evaluated under dry sliding conditions. A certain part of the
$ I, H- y, p% n6 ~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
+ _4 ?  c" @/ k  ypart 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
$ p& _( d& q; Oas-cast and the aged samples were fully characterised before and after the wear testing using hardness, profilometer, scanning
  z( C8 V# y; C* @+ I/ [+ helectron microscopy (SEM), optical microscopy, X-ray diffraction, and energy dispersive detector (EDS). The wear tests using
% j3 O  C! ~$ k  Z+ Z& M+ `on a pin-on-disc machine showed that the aging treatments improved the wear behaviour of AA 6063 alloy compared to as-cast
samples.
