本文采用化学处理方法在ti40zr10cu34pd14sn2块状非晶合金表面制备了生物活性层。在形成磷灰石层之前，将所有样品浸泡在混合酸（hno3和HF）水溶液中，并在1.2M NaOH水溶液中煮沸。然后，将它们浸泡在模拟体液（SBF）中，在表面形成磷灰石层。采用x射线衍射（XRD）、x射线光发射光谱（XPS）和环境扫描电镜（ESEM）对磷灰石层进行了表征。结果表明：预钙化ti40zr10cu34pd14sn2块状非晶合金在SBF中快速沉积了致密均匀的以HA和ca2p2o7为主的磷酸钙层；
In the present paper, a chemical treatment method has been employed to prepare a bioactive layer on the surface of Ti40Zr10Cu34Pd14Sn2bulk glassy alloy. Prior to forming an apatite layer, all samples were dipped in mixed acid (HNO3and HF) aqueous solution and boiled in 1.2M 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 Ca2P2O7was rapidly deposited on the pre-calcified Ti40Zr10Cu34Pd14Sn2bulk glassy alloy in SBF within 7 days.
