Interfaces Between Metal and Ceramics and Their Microstructures in Bio-material
生物材料中金属-陶瓷界面和微结构

The present research shows that the composite with Ti (or its alloys) as a substrate andcommercial porcelain as its coating has been proved to be quite effective to resolve bio-compatibilityproblem since the porcelain, which contains mainly Al2O3 ) SiO2, K2O, Na2O, possesses best biocompatibility with human tissues. Moreover, the above composite adding a thin layer of Si3N4between the Ti substrate and porcelain coating has been proved to be even more effective toresolve present problem due to the adhesion between the substrate and the porcelain coatingquite strengthened. These composites are successfully applied to the present application andmay open new application fields since the problems have been effectively 'resolved. The presentinvestigation not only gives the chemical composition, the technical process and the performanceo f the composites, but also gives their microstructure details.
