| Outline of Final Research Achievements |
For the bonding mechanism of the interface between zirconia and porcelain, though clear diffusion reaction of the constituent elements could not be confirmed, then there were fine asperities on the surface, amorphous dense contact was confirmed. Thus, both combind was estimated to be due to the anchor effect and van der Waals forces of the amorphous phase having an irregular and high density of zirconia surface of the amorphous layer at the interface. Also, the bonding strength was estimated that depends heavily on the mechanical strength of the members forming.
For bioactive processing zirconia surface, if fired at an appropriate temperature by applying a high calcium acetate solubility, it was suggested that it is possible to introduce the calcium ions on the surface without reducing the mechanical strength .
