Özet

In this study, the wear behaviors of SiO2 reinforced AA7075 matrix composites produced by pressureless infiltration method were investigated in the scope of the work, 10%, 20%, 30%, and 40% SiO2 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 SiO2 amount and hardness values were increased by increasing SiO2 amount. In addition the weight loss and friction coefficient were decreased depending on increasing of SiO2 amount.
