Summary A porous Ti-16Sn-4Nb alloy with an average pore size of 300 µm and porosity of 60 % was prepared by powder metallurgy, and a bone-like apatite coating was obtained by soaking the samples in a concentrated simulated body fluid (lOx SBF). The changes of the microstructure and composition on the surface with soaking time were investigated by using X-ray diffractometry (XRD), and scanning electron microscopy equipped with energy dispersive spectroscopy (SEM-EDS), The bone-like apatite granules started to deposit throughout the porous Ti alloy foam aner 1 h soaking, and the number of granules increased with the increase of the soaking time. A uniform bone-like apatite layer covered the entire surface of the sample after soaking in Ihe lOx SBF for 6h. The Ti-16Sn-4Nb foam showed a good bioactivity after a thermochemical process and soaking into a 1Ox SBF.
