Bu derlemede karbon siyahı, grafit, karbon nanotüp ve grafen takviyeli titanyum matrisli kompozit üretimi üzerine yapılan çalışmalar özetlenmiştir. Özellikle grafen takviyesinin önemi vurgulanmış ve gelecekte titanyum kompozitler için yeni eğilimlerin ne olacağı ortaya konulmuştur. Ayrıca, yapılan takviyelerin kompozit mekaniği üzerine olan etkileri mukavemet artırıcı mekanizmalarla açıklanmıştır. Karbon esaslı malzemelerden biri olan grafen bir atom kalınlığında olup, ilk kez 2004 yılında sentezlenmiş ve 2008 yılından itibaren metal matrisli kompozit üretiminde kullanılmaya başlanmıştır. Son yıllarda titanyum matrisli kompozit üretiminde de tercih edilmektedir. Grafen ve diğer karbon esaslı takviye malzemeleri kıyaslandığında, grafen takviyesi ile daha yüksek sertlik, akma ve çekme dayanımı elde edilmiştir. Literatürde grafen miktarının, sinterleme sıcaklığı ve zamanının, toz metalürjisi süreçlerinin ve ikincil işlemlerin kompozitin mekanik özelliklerine etkisi yeterince ortaya konulmamıştır. Bu durum titanyum esaslı malzemelerde grafen kullanımına yakın gelecekte de devam edileceğini göstermektedir. Bu nedenlerle, özellikle grafen takviyeli yeni nesil titanyum kompozitler sahip olduğu hafiflik, yüksek mukavemet, yüksek aşınma ve korozyon daynımından dolayı yakın gelecekte implant, otomotiv, savunma sanayi, havacılık ve uzay uygulamalarında kullanım alanı bulacaktır.
This collection summarizes the studies on the production of carbon black, graphite, carbon nanotype and graphene supplement titanium matrix composite. The importance of graphene supplement has been emphasized in particular and it has been revealed what new trends will be for titanium composites in the future. Furthermore, the effects of the supplements on the composite mechanics are explained by strength enhancing mechanisms. Graphene, one of the carbon-based materials, is in an atomic thickness, first synthesized in 2004 and began to be used in the production of composite with metal matrix since 2008. In recent years, it has also been preferred in the production of titanium matrix composite. Compared to graphene and other carbon-based supplements, greater hardness, flow and drawing resistance has been obtained with graphene supplement. In literature, the impact of the quantity of graphene, the synthesis temperature and time, the powder metallurgy processes and secondary processes on the mechanical characteristics of the composite has not been sufficiently revealed. This situation shows that graphene in titanium-based materials will continue to be used in the near future. For these reasons, the new generation of titanium compounds, especially graphene supplement, will find the area of use in implant, automotive, defense, aviation and space applications in the near future due to its lightness, high strength, high stretching and corrosion resistance.
In this review, the studies on titanium matrix composites reinforced with carbon black, graphite, carbon nanotube and graphene are summarized. Especially, the importance of graphene reinforcement has been emphasized, and new trends for titanium composites will be addressed in the future. Furthermore, the effects of the reinforcements on the composite mechanics are explained by strengthening mechanisms. Graphene is one of the carbon-based materials which has one atomic thickness. It was first synthesized in 2004 and started to be used in metal matrix composite fabrication from 2008. Graphene is also preferred in the production of titanium matrix composite in recent years. When graphene is compared with other carbon based reinforcing materials, titanium composites with graphene addition have high hardness, high corrosion resistance, greater yield and tensile strength. In the literature, the effect of the amount of graphene, sintering temperature and time, processes of powder metallurgy method and secondary processes on the mechanical properties of the titanium composites have not been sufficiently revealed. Therefore, the use of graphene in titanium based materials will continue to be used in the near future. Because of these considerations, new generation titanium composites, especially with graphene additives, will be used in implant, automotive, defense industry, aerospace and space applications in the near future due to their lightness, high strength, high wear and corrosion resistance.
