在含β-Ca3(PO4)2晶体的微晶玻璃层上加入成分为60CaO·30P2O5·7Na2O·3TiO2的玻璃粉末，在800℃的空气中加热，可以很容易地将含有β-钛相的新型钛合金(Ti-29Nb-13Ta-4.6Zr)连接起来。拉伸结合强度测试表明，涂层与基材之间的结合非常牢固。即使在钛合金的大变形(如弯曲角度≈90°)后，涂层也没有从基材上剥落。在加热过程中，TiO22O5-Na2O-CaO系钛合金表面会自动形成成分梯度层，形成强连接。在37℃的模拟体液中浸泡，涂层表面新生成了羟基磷灰石相。
A glass-ceramic layer containing β-Ca3(PO4)2crystals could be joined easily with a new type of titanium alloy (Ti–29Nb–13Ta–4.6Zr) consisting of a β-titanium phase by heating the metal, on which glass powders with a composition of 60CaO·30P2O5·7Na2O·3TiO2were placed, at 800°C in air. Measurement of tensile bonding strength revealed that the joining between the coating layer and the substrate is very strong. Even after the large deformation (e.g., ≈90° in bending angle) of the titanium alloy, the coating layer was not peeled off from the substrate. A compositionally gradient layer in the TiO2–P2O5–Na2O–CaO system is developed automatically on the titanium alloy during the heating, resulting in the formation of the strong joining. By soaking in simulated body fluid at 37°C, hydroxyapatite phase was formed newly on the surface of the coating layer.
