通过硫酸处理在钛（Ti）板表面形成许多微孔，然后通过在模拟体液（SBF）中使用电磁感应直接加热钛板，在钛板的孔中沉淀磷灰石核。当钛板在模拟体液中浸泡时，6 h内无定形磷酸钙薄膜覆盖整个钛板表面，12 h内生长成羟基磷灰石。由于微孔中生长的羟基磷灰石与钛板之间的机械联锁效应，羟基磷灰石层对钛板表现出高的粘合强度。
Many micro pores were formed on the surface of a titanium (Ti) plate by sulfuric acid treatment, then apatite nuclei were precipitated in the pores of the Ti plate by direct heating of the plate by using electromagnetic induction in a simulated body fluid (SBF). When the Ti plate was soaked in SBF, amorphous calcium phosphate thin film covered the whole surface within 6 h and it grew into hydroxyapatite within 12 h. The hydroxyapatite layer showed high adhesive strength to the Ti plate due to a mechanical interlocking effect between hydroxyapatite grown in the micro pores and the Ti plate.
