摘要
Scaffold-like hydroxyapatite/tri-calcium-phosphate (HA/TCP) coatings have been deposited on strong zirconia-substrates using a unique HA-slip coating-deposition and coating-substrate co-sintering process. Bending strength of such layered composites is over 300 MPa, higher than the upper strength limit of natural bones. Thick scaffold-like HA-coatings with open pores larger than 100 mu m can be deposited onto the micro-porous HA/TCP surface using the same technique. Such load-bearing %26quot;HA-scaffolds%26quot; with adequate bending strength and large open pore structures provide useful options as load-bearing bone implants.
