Bu çalışmada, döküm yöntemi ve döküm sonrası 600°C’de 2 saat sinterleme uygulanarak, %10/20 B4 C takviyeli ve AA2014 matris yapılı kompozit malzemeler üretilmiştir. Döküm yöntemi ile üretilen numunelere, sinterleme ve takviye oranlarının aşınma davranışlarına etkileri incelenmiştir. Çalışmada mikroyapı incelemeleri amaçlı; Taramalı elektron mikroskobu (SEM), Element Dağılım Spektrometresi (EDS) ve X-Ray incelemeleri yapılmıştır. Sertlik sonuçları için HV1 yöntemi ile makro sertlik verileri alınmıştır. Aşınma işlemi için pin-on-disk tipi kuru aşınma cihazında, 0.5MPa basınç altında, 1 ms-1 kayma hızında ve dört farklı kayma mesafesindeki veriler kullanılmıştır. Artan B4 C takviye oranı ve sinterleme işlemleri sonrasında sertlik artmış, sürtünme katsayısı düşmüş ve aşınma kaybı azalmıştır. En düşük sürtünme katsayısı ve aşınma kaybı 600 °C’de 2 saat sinterlenen %20 B4 C içeren numunede elde edilmiştir.

In the study, AA2014 matrix and 10/20% B4 C reinforced composites structure have been produced by casting and casting + sintering processes (at 600 °C for 2 hours). The effects of sintering and reinforcement ratios on wear behavior of specimens have been investigated after casting. For investigation of the microstructure studies; Scanning Electron Microscopy (SEM), Element Distribution Spectrometer (EDS) and X-ray studies have been performed. Macro hardness data have been obtained by HV1 method. For wear tests, pin-on-disc type dry abrasion device has been used at a pressure of 0.5 MPa, a sliding speed of 1 ms-1 and at four different slip distances. After sintering and increasing the B4 C reinforcement ratio, the hardness values increased, the friction coefficient decreased and the wear loss decreased. The lowest coefficient of friction and loss of wear have been obtained with the sample containing of 20% B4C sintered at 600 °C for 2 hours.
