本文通过界面结合强度测试,电子探针X射线显微分析(EPMA),对两种生物活性玻璃涂层—钛的界面的结合强度进行了考查,并分析了生物陶瓷涂层复合体的界面结构及其与结合强度的关系。结果表明:两种生物活性陶瓷涂层复合体的界面能够传递相应的生理负荷,氧化膜及界面元素弥散决定着陶瓷与钛的结合强度,可切削性玻璃陶瓷涂层复合体与混合玻璃陶瓷涂层复合体相比,前者的界面有明显的氧化层,钛弥散度较宽,剪切强度较高。
In this paper, the binding strength of the two bioactive glass coating-titanium interfaces was examined by the interface bonding strength test and the electron probe X-ray microanalysis (EPMA), and the interface structure of the bio-ceramic coating composite body And its relationship with the bonding strength. The results show that the interface between the two bioactive ceramic coating composites can transfer the corresponding physiological load, the oxide film and interface element dispersion determine the bonding strength between ceramic and titanium, the machinability glass ceramic coating composite and mixed glass ceramic coating Compared with the layer composite, the interface of the former has obvious oxide layer, the dispersion of titanium is wider and the shear strength is higher.
