摘要： 本研究在钛合金表面施加与人体组织相容性极好的商业医用P-陶瓷（含Al2O3，SiO2，K2O,Na2O等）涂层，在提高与人体组织相容性方面，收到了显著的效果．而在此之前，在钛合金表面上施加Si3N4涂层，由干有效地增强了钛合金与陶瓷涂层之间的结合强度；使效果更佳．这一复合涂层体系的成功，解决了目前遇到的问题，开创了不少新的应用领域．本研究不但给出复合涂层化学组成、工艺和性能，并且对其显微结构进行了深入地研究．

Abstract: The present research shows that the composite with Ti (or its alloys) as a substrate and commercial porcelain as its coating has been proved to be
quite effective to resolve bio-compatibility problem since the porcelain, which contains mainly Al2O3, SiO2, K2O, Na2O, possesses best bio-
compatibility with human tissues. Moreover, the above composite adding a thin layer of Si3N4 between the Ti substrate and porcelain coating has
been proved to be even more effective to resolve present problem due to the adhesion between the substrate and the porcelain coating quite strengthened.
These composites are successfully applied to the present application and may open new application fields since the problems have been effectively resolved. The present investigation not only gives the chemical composition, the
technical process and the performance of the composites, but also gives their microstructure details.

Key words: Ti-alloy-ceramic interface, Si_3N_4 coating,electron microstructure
