Abstract:

With an increasingly aging population and improvement of living standards, there is a rising demand for new biomaterials to replace or repair structural (load-bearing) components of the human body. Nowadays, Ti and its alloys are commonly used for implant devices that replace patient�s hard tissues. However, these implants are composed from harmful elements like Al, Mn, Cr, V, Co, Ni etc. From our point of view is therefore necessary to develop a low-density alloy with a high hardness that will be biocompatible and cost-effective. We focuse on preparation and characterization of a Ti-Si alloys. Both Ti and Si are biocompatible elements and additionaly Si supports bone calcification. We prepared five types Ti-Si alloys. Only one alloy from five is composed of one sole phase Ti5Si3 alloy. Microstructure was examined by synchrotron X-ray diffraction and high resolution transmission electron microscopy. This alloy is almost 300% harder compared the implants used today. Mass density of the alloy is 4.27 g/cm3, while modulus of elasticity is 187 GPa. All prepared Ti-Si alloys are biocompatible measured in respect to MC3T3E1 mouse preosteoblastic cells. In the talk I will present preparation, phase composition, microstructure morphology, biocompatibility and basics mechanical properties of five different Ti-Si alloys.
