Abstract

Toz
metal kompaktların sıcak ekstrüzyonu ile üretilen ve farklı oranlarda 32 µm
boyutlu SiC partiküller ile takviye edilen AA7075 Al matrisli
kompozitlerin  mikroyapı, sertlik ve
tribolojik performansına T6 ve T73 ısıl işlemlerinin etkisi incelendi. Bu amaçla,
soğuk olarak preslenmiş farklı SiC partikül içeriğine sahip AA7075 toz metal
kompaktlar 480 °C’de, 12 mm çaplı çubuklar halinde ekstrüze edildi. T6 ve T73
ısıl işlemlerinin uygulandığı ekstrüze edilmiş numunelerin mikroyapı, sertlik
ve tribolojik karakteristikleri tarama elektron mikroskobu (SEM), enerji dağınımlı x-ray analizör (EDX), brinell sertlik ve adhesif aşınma test ve analizleri ile incelendi. Deneysel sonuçlar,
SiC partikül içeriğinin artmasına bağlı olarak kompozitin sertlik ve
aşınma direncinin de arttığını göstermektedir. Ayrıca, T6 ısıl işlemli
numunelerin T73 ısıl işlemli numunelere göre daha iyi sertlik, sürtünme ve
aşınma performansı gösterdiği tespit edildi.
