钛基生物搪瓷的活性研究

摘要

The chemistry change on the surface of bioenamel based on the titanium wasinvestigatodby soak in simulated body fluid and implanting into bone of animal and using means of SEM/EDAX,thin film XRD,atomie absorption spectral analysis,et al.The results showedthat hydroxyapatite layer on the surface of this bioenamel can be formed in physiologicalenvironment.So it has biological activity,and implantment in animal bone shows high jointstrength and goood body adaptability.
