Abstract

A new system of functionally graded materials is considered in this study. The samples were obtained by sintering titanium with hydroxyapatite powders. Hydoxyapatite type grains were prepared by sol-gel method. The sintering conditions lead to convenient values of samples density as compared with bone density. The bioactivity was tested in simulatated body fluid (SBF). The size of hydroxyapatite type phases developed at the sample surface after soaking for a week in SBF is about hundreds of micrometers and tend to form a continuous network of the new developed bioactive layer..
