Notes:
In the event of a significant injury, human bone must be repaired by artificial means. In the presentstudy, we used titanium (Ti) to create a scaffold for cell renewal with an emphasis on strength.Because scaffolds for cell renewal require a microporous structure that enables supply of oxygenand nutrients, sintered Ti fiber was used. However, although titanium has a high fracture toughness,it does not bind to hydroxyapatite (HAp), the main component of bone, and thus requires additionof bioactivity. Following treatment by sodium hydroxide, titanium fibers were heated and immersedin simulated body fluid. Through this process, HAp was formed on the titanium surface to create abioactive material with both a high strength and biocompatibility. Following approximately twoweeks of immersion in simulated body fluid, HAp was formed such that it covered the surroundingsof titanium fibers without any gaps. In addition, the fracture condition of HAp was analyzed byconducting mechanical tests, such as tensile strength and compression tests, on the titanium fiberson which HAp was formed. Furthermore, collagen coating was performed on the titanium surface,and the material was immersed in simulated body fluid to investigate and compare HAp formation
