Research Abstract

Ti-xMg (x=0, 17, 33, 55, and 100 mass%) alloys, which can be applied to structural and biomedical materials, were fabricated by direct current magnetron sputtering. The crystal structures and surface chemical states of Ti-xMg alloys were investigated by X-ray diffraction method and X-ray photoelectron spectroscopy, respectively. In addition, dissolution amounts of Ti and Mg were evaluated by immersion in 0.9% NaCl at 310 K for 7days. The ability of bone formation was investigated by immersion in Hanks' solution at 310 K for 30 days. The dissolution amounts of Ti after immersion in 0.9% NaCl at 310 K for 7d were below detection limit, whereas the dissolution of Mg occurred from Ti-xMg alloy. The dissolution amounts of Mg increased in Ti-55Mg alloy and Mg. Calcium phosphate was precipitated on the surface of only Ti-33Mg alloy after immersion in Hanks' solution for 30 d.
