Farklı oranlarda titanyum içeren toz metalurjik malzemeler sıcak presleme yöntemiyle sinterlenerek üretilmiştir. Üretilen malzemelerin yoğunlukları, mikroyapısal özellikleri, sertlikleri ve aşınma dayanımları incelenmiştir. Ayrıca aşınma mekanizmasının belirlenebilmesi için aşınma testi sonrası malzemelerin aşınmış yüzeyleri tarama elektron mikroskobu kullanılarak incelenmiştir. Yapılan incelemeler sonucunda titanyum partikülleri etrafında farklı katmanlardan oluşan intermetalik fazlar oluştuğu belirlenmiştir. Oluşan intermetaliklerin malzemenin sertliğini ve aşınma dayanımını arttırdığı tespit edilmiştir. Ayrıca aşınmış yüzeylerde yapılan incelemeler malzemenin sertliğinin değişmesiyle birlikte aşınma mekanizmasınında değiştiğini ortaya koymuştur. Copper samples with different titanium contents were produced using hot pressing technique. Densities, microstructures, hardness and wear resistances of the produced specimens were investigated. Also to understand the operating wear mechanisms during wear tests worn surfaces of the speciemens were investigated under scanning electron microscope. Microstructural investigations showed that different intermetallic layers were formed around titanium particles. Formation of these intermetallic phases increased hardness and wear resistance of the material. Worn surface investigations showed that change of hardness also changes the wear mechanisms that cause wear damage during wear tests.
Metal materials containing titanium in different proportions are produced by synthesizing with a hot pressing method. The intensity of the manufactured materials, microbuilding properties, hardness and stretching resistance have been studied. Furthermore, to determine the coating mechanism, the coating test sub-material coated surfaces have been studied using an electron microscope to scan. The results of the studies have found that intermetal phases formed from different layers around titanium particles. It has been found that the formed intermetalics increase the hardness and resistance of the material. Studies on exhausted surfaces also showed that the hardness of the material changes in the exhausting mechanism.
