Ti-Si alloys – Materials for implants applications

ith 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/cm
3
,
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.
