Abstract

In this study, the wear behaviors of SiO 2 reinforced AA7075 matrix composites produced by pressureless infiltration method were investigated in the scope of the work, 10%, 20%, 30%, and 40% SiO 2 were added into AA7075 Al alloy and produced by infiltration method. Produced samples’ density values were measured by Archiment method, hardness values were measured in micro hardness device under 2 N load. Wear tests were performed using 1 ms -1 sliding speed at five difference sliding distance under 15 N load by pin-on-disc type apparatus. As a result of the study, the density values were decreased by increasing SiO 2 amount and hardness values were increased by increasing SiO 2 amount. In addition the weight loss and friction coefficient were decreased depending on increasing of SiO 2 amount.

Özet

Bu çalışmada, basınçsız infiltrasyon yöntemiyle üretilmiş olan SiO 2 takviyeli AA7075 matrisli kompozitlerin aşınma davranışları incelenmiştir. Çalışma kapsamında 7075 Al alaşımı içerisine %10, 20, 30 ve 40 takviye-hacim oranı oluşturacak şekilde farklı oranlarda SiO 2 ilave edilerek infiltrasyon yöntemiyle üretilmiştir. Üretilen numunelerin yoğunluk ölçümleri Arşimet prensibine göre, sertlik ölçümleri ise mikro sertlik cihazında 2 N yük uygulanarak Vickers olarak ölçülmüştür. Aşınma testleri pin-on-disk tipi aşınma cihazında 1 ms -1 kayma hızında 15 N yük altında beş farklı kayma mesafesinde test edilmiştir. Yapılan çalışmalar sonucunda, takviye elemanı olarak AA7075 alaşımına ilave edilen SiO 2 miktarı arttıkça, kompozitlerin yoğunlukları azalırken sertlikleri artmaktadır. Bununla birlikte, ilave edilen SiO 2 miktarındaki artışa bağlı olarak alüminyum kompozitlerin ağırlık kaybının ve sürtünme katsayılarının da azaldığı belirlenmiştir.
