Influence of Cu Addition on Dry Sliding Wear Behaviour of A356 Alloy

Abstract: Influence of addition of copper (Cu) on the dry sliding wear behavior of A356 alloy has been reported in the paper. Effect of load, composition and sliding distances on A356 alloy before and after addition of Cu has been studied. Wear test surfaces were examined by SEM/EDX. It was found that wear resistance of A356 alloy decreases with increase in applied normal pressures and sliding distances. However, wear resistance of A356 alloy increased with Cu addition. Increase in wear resistance is mainly because of i… Show more

“…Moreover, the presence of coated alumina nanoparticles decreases the ability of copper for plastic deformation and removal leading to the lower abrasive wear rate. Similar observations for wear rate behavior of Al 2 O 3 reinforced copper matrix composites [55][56][57][58][59]. Figure 7 represents also the change of abrasive wear rate versus sliding speed for copper alumina coated by silver nanocomposite at a constant load of 10 N. Abrasive wear rates increases with increasing sliding velocity for all the tested specimens.…”

“…Yukarıda belirtilen endüstriyel alanlardaki uygulamalarda Al alaşımları genellikle mekanik ve tribolojik zorlamalara maruz kalmaktadır. Al alaşımlarının mekanik ve tribolojik özellikleri içerdikleri alaşım element(ler)i, alaşım element(ler)inin oranı ve alaşım element(ler)inin yapısal özelliklerde neden olduğu değişim, üretim yöntemi ve uygulanan ısıl işleme göre farklılık göstermektedir [5][6][7]. Al esaslı alaşımlarda en çok kullanılan alaşım elementi silisyum (Si) olup, %50'ye kadar silisyum içerebilen birçok Al-Si ve Al-Si esaslı ticari ve standart alaşım mevcuttur [3,8,9].…”

“…Ötektikaltı alaşımlar mekanik özelliklerin ön planda tutulduğu uygulamalarda, ötektiküstü olanlar ise daha çok sertlik ve aşınma direncinin önemli olduğu uygulamalarda tercih edilmektedir [14,15]. Al-Si esaslı alaşımların mekanik ve tribolojik özellikleri silisyum oranının yanı sıra içerdikleri diğer alaşım element(ler)inin türüne ve miktarına bağlı olarak da değişmektedir [5][6][7]. Bakır (Cu) ve magnezyum (Mg) katkılarının sertlik ve mukavemeti artırmanın yanı sıra bu alaşımları ısıl işleme elverişli hale de getirdiği bilinmektedir [16,17].…”
