The method of the proton induced x-ray emission ( PIXE ) was used for the investigation of ion exchange processes on the surface of intramuscularly implanted Bioglass-Ceramics. This method allows a simultaneous analysis free from destruction in concentrations ranges of ppm for several elements. The measurements were carried out with different proton energy, in that manner a relative quantity analysis was possible in different layers. A durable two-layered surface already originates in a short time after the implantation on the implant interface. This one consists of a layer rich in calcium and phosphorus as well as a second zone rich in silicon. The meaning of this two-layered surface for the bio-activity and the bio-stability of the material is discussed.
采用质子激发X射线发射（PIXE）方法研究了肌肉内植入生物玻璃陶瓷表面的离子交换过程。该方法能够在ppm浓度范围内对多种元素进行无损同步分析。测量在不同质子能量下进行，从而能够对不同层进行相对定量分析。植入后短时间内，植入物界面就会形成持久的双层表面。该双层表面由富含钙和磷的一层以及富含硅的第二层区域组成。讨论了这种双层表面对材料生物活性和生物稳定性的意义。
