Description

In the present paper, a chemical treatment method has been employed to prepare a bioactive layer on the surface of Ti40Zr10Cu34Pd14Sn2 bulk glassy alloy. Prior to forming an apatite layer, all samples were dipped in mixed acid (HNO3 and HF) aqueous solution and boiled in 1.2 M NaOH aqueous solution. Then, they were soaked in simulated body fluid (SBF) to form an apatite layer on the surface. The apatite layer was characterized by X-ray diffraction (XRD), X-ray photoemission spectroscopy (XPS) and environment scanning electron microscopy (ESEM). The results show: a dense and uniform calcium phosphate layer mainly composed of HA and Ca2P2O7 was rapidly deposited on the pre-calcified Ti40Zr10Cu34Pd14Sn2 bulk glassy alloy in SBF within 7 days.
