Abstract: Anodic alumina containing calcium (AACC) was prepared by a joint method of anodization and electrodeposition. The morphology and composition of AACC were studied by scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS), respectively. The chemical stability and induction ability of AACC in a simulated body fluid (SBF) were also investigated by inductively coupled plasma/atomic emission spectroscopy (ICP/AES), pH meter and X-ray diffractrometry (XRD). The results show that the calcium content in anodic alumina varies with electrodeposition voltage within a range 1%-10% in 10 g/L calcium salt solution. The as-prepared AACC exhibits high chemical stability and can induce the formation of bone-like apatite in SBF.
