Development of bio-materials: Bio-active calcium phosphate-coated medical implant and Au-based dental alloys

Fabrication process and properties of Au-based alloys and Ti implant for medical application were investigated in this work. The topics include 1.) bonding strength between Au-based alloy and porcelain, 2.) bulk strength of In-added Au-12Pt-0.6Cu-0.5Sn-xIn alloy, and 3.) bioactive calcium phosphate-coated Ti implant. For each dental material, microstructure and properties were discussed as a function of processing variables.
