Özet:

 In this study, composites with 7075 aluminum alloy matrix 5, 10, 15 and 20 Magnesia reinforced at different ratios were produced by powder metallurgy method. Wear tests were carried out by applying a load of 40 N, at a speed of 0.9 ms-1, at wear distances of 90 m and 180 m. Then, abrasive wear tests of the composites were carried out. The data obtained from the experiments were interpreted together with the microscope images. The effects of different MgO reinforcement ratios, wear distances, sintering temperatures and times on the abrasive wear behavior of the composites were evaluated. It has been observed that although the wearing distance has increased by two times, the wear losses have not increased at the same rate, but have occurred less frequently. It has been evaluated that the MgO reinforcement agglomerations and porosity occurring in the composite structure have an effect on the mechanical properties. It was observed that the eroded surface morphology occurred mostly in the form of micro-ploughing mechanism. It was concluded that the most effective parameter on the wear behavior of the composites is the amount of MgO reinforcement, and that the changes in sintering temperature and time do not have a significant effect.

 Bu çalışmada 7075 alüminyum alaşımı matrisli, 5, 10, 15 ve 20 oranlarında Magnezya takviyeli kompozitler toz metalürjisi yöntemiyle üretilmiştir. Daha sonra kompozitlerin abrasif aşınma deneyleri gerçekleştirilmiştir. Aşınma deneyleri 40 N yük uygulanarak, 0,9 ms-1 hızda, 90 m ve 180 m aşınma mesafelerinde yapılmıştır. Deneylerden elde edilen veriler mikroskop görüntüleriyle birlikte yorumlanmıştır. Farklı MgO takviye oranları, aşınma mesafeleri, sinterleme sıcaklıkları ve sürelerinin kompozitlerin abrasif aşınma davranışı üzerindeki etkileri değerlendirilmiştir. Aşınma mesafesinin iki kat artmasına rağmen aşınma kayıplarının aynı oranda artmadığı daha az meydana geldiği görülmüştür. Kompozit yapıda meydana gelen MgO takviye topaklanmaları ve gözenekliliğin mekanik özellikler üzerinde etkili olduğu değerlendirilmiştir. Aşınmış yüzey morfolojisinin daha çok mikro-sabanlama mekanizması şeklinde gerçekleştiği görülmüştür. Kompozitlerin aşınma davranışı üzerinde en etkili parametrenin MgO takviye miktarı olduğu, sinterleme sıcaklığı ve süresindeki değişimlerin çok önemli oranda etki yapmadığı genel sonucuna varılmıştır.
