Deposition of Ca/P layer on the surface of TiZrCuPd glassy alloy

In the present paper,electrochemical method was used to build a porous surface on the Ti-based glassy alloy to improve its bioactivity.Bone-like apatite layer was successfully prepared on the porous surface.Morphology,phases,composition and chemical valence were investigated using scanning electron microscopy (SEM),X-ray diffraction(XRD)and X-ray photoelectron spectrum (XPS).The results show:a homogenous porous surface can be built in 10% HNO3under 2Vpotential for 1hat 60℃on the Ti40Zr10Cu36Pd14g lassy alloy; bone-like Ca/P layer can deposits rapidly on the glassy alloy with the porous surface in a simulated body fluid (SBF);the bone-like Ca/P layer is mainly composes of hydroxyapatite(HA).
