T/M YÖNTEMİ İLE ÜRETİLEN Cu-C-Al2SiO5 KOMPOZİTİNİN ABRASİV AŞINMA DAYANIMI

Bu çalışmada, Cu tozuna hacimce %5, %10, %15 oranında C ve Al2SiO5 katılaraktoz metalurjisi yöntemi ile üretilen Cu-C-Al2SiO5 kompozitinin abrasiv aşınmadavranışı üzerinde karbon ve alüminyum silikat takviye partiküllerinin etkisiaraştırılmıştır. Aşınma deneyleri farklı yükler kullanılarak pim-disk aşınmaaparatında yapılmıştır. Numunelerin Mikroyapıları SEM, optik mikroskop, EDS veX-Ray ile incelenmiştir. Sonuç olarak bakır matrise katılan C ve Al2SiO5 takviyepartiküllerinin hacim oranının ve uygulama yükünün artmasıyla aşınma oranınınarttığı tespit edilmiştir.

THE INVESTIGATION OF ABRASIVE WEAR OF Cu -C -Al2SiO5 COMPOSITE PRODUCED BY P/M PROCESS

In this study, the effect of C and aluminium silicate (Al2SiO5 ) onabrasive 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 theexperiments, wear resistance of samples were determined using different loads bypin on disc wear apparatus. Microstructures of samples were examined by opticaland scanning electron microscopies,EDS and x-Ray diffraction methods. Finally, ithas been found that with the increasing C ve Al2SiO5 reinforcing particles andloads, wear rate increased.
