Title: Attempt to develop Ti-based amorphous alloys for biomaterials
Abstract: The purpose of the present study is to develop a biocompatible Ti-based amorphous alloy. We examined mechanical and chemical properties of newly developed Ti-based amorphous alloys in comparison with pure Ti metal and Ti–6Al–4V alloy which have been used at present for biomaterials. Ti-based multi-component alloys do not contain Al and Ni elements which are the origin for cytotoxicity and neurotoxicity. The amorphous alloy ribbons were prepared by the single roll melt-spinning method. The Ti-based amorphous ribbons exhibited good bend ductility, higher strength and lower Young's modulus than pure Ti and Ti–6Al–4V alloy. In addition, Ti-based amorphous alloys had an excellent potentiality of corrosion resistance that was passivated in wide passive range and at the lower passive current density of approximately 10−2 A m−2 in 1 mass% lactic acid, 3 mass% NaCl and PBS(−) solutions at 310 K.
