    Effect of Age Hardening on the Wear Behaviour of the Al-7Si-4Zn-3Cu Alloy
    (Kırıkkale Üniversitesi, 2019) Alemdağ, Yasin; Beder, Murat
    In this study, the friction and wear properties of the Al-7Si-4Zn-3Cu alloy aged T6 and T7 conditions after its solutionizing and quenching treatment were investigated. The results obtained from heat treated alloy were compared to its as-cast state. The friction coefficient of the alloy increased but its volume loss decreased after the T6 and T7 heat treatments. It was especially observed that the alloy aged T6 and T7 conditions exhibited higher wear resistance than its as-cast state at high load and sliding speed. On the other hand, T6 heat treatment was determined to be more powerful effect than the T7 to improve the wear resistance of the alloy. The results obtained were explained in terms of the hardness and strength of the alloy with its wear mechanism at both heat treated and as-cast states.
