Aluminum matrix composites have attractive
attention for scientists and manufacturers. In this study, fullerene (C60)
nanoparticle reinforced aluminum matrix composite was fabricated via semi
powder metallurgy method. Development of mechanical performance of pure
aluminum was aimed using C60 nanoparticle. Microstructure analyzes were
completed by X-ray diffraction (XRD) and Scanning Electron Microscope (SEM).
Hardness, compression and tensile properties of unreinforced aluminum and C60
reinforced composite were evaluated. Results show that nanoparticle was
homogenously distributed in matrix and there were no cracks or macro defects.
Hardness was significantly improved with the addition of fullerene and
extrusion process. Al-C60 composite exhibited better compression and tensile
performance than pure aluminum.

    Alüminyum matrisli kompozitler sanayiciler
ve bilim insanları için dikkat çekici bir öneme sahiptir. Bu çalışmada fulleren
(C60) takviyeli alüminyum matrisli kompozit malzeme, yarı toz metalürjisi
yöntemiyle üretilmiştir. X Işını Kırınımı (XRD) ve Taramalı Elektron
Mikroskopuyla (SEM) numunelerin mikro yapı analizleri gerçekleştirilmiştir. Saf
alüminyum ve Al-C60 kompozitinin sertlik, basma ve çekme mukavemetleri hakkında
değerlendirmeler yapılmıştır. Sonuçlardan yola çıkarak, fullerenin alüminyum
matrisi içerisinde homojen dağıldığı gözlemlenmiştir ve herhangi bir çatlağa ya
da makro hatalara rastlanmamıştır. Fullerenin ilavesiyle ve ekstrüzyon
prosesiyle alüminyumun sertliğinde önemli bir artış görülmüştür. Al-C60
kompoziti saf alüminyuma kıyasla daha iyi basma ve çekme mukavemeti
performansları sergilemiştir.
