In this study, the effect of C and aluminium silicate (Al2SiO5 ) on

abrasive wear of Cu-C -Al2SiO5 composite produced by powder metallurgy route,

containing 5, 10, 15 vol. % C and Al2SiO5 in Cu matrix was investigated. In the

experiments, wear resistance of samples were determined using different loads by

pin on disc wear apparatus. Microstructures of samples were examined by optical

and scanning electron microscopies,EDS and x-Ray diffraction methods. Finally, it

has been found that with the increasing C ve Al2SiO5 reinforcing particles and

loads, wear rate increased.

Bu çalışmada, Cu tozuna hacimce %5, %10, %15 oranında C ve Al2SiO5 katılarak

toz metalurjisi yöntemi ile üretilen Cu-C-Al2SiO5 kompozitinin abrasiv aşınma

davranışı üzerinde karbon ve alüminyum silikat takviye partiküllerinin etkisi

araştırılmıştır. Aşınma deneyleri farklı yükler kullanılarak pim-disk aşınma

aparatında yapılmıştır. Numunelerin Mikroyapıları SEM, optik mikroskop, EDS ve

X-Ray ile incelenmiştir. Sonuç olarak bakır matrise katılan C ve Al2SiO5 takviye

partiküllerinin hacim oranının ve uygulama yükünün artmasıyla aşınma oranının

arttığı tespit edilmiştir.
