A new method of apatite coating on yttria partially stabilized zirconia plate was studied. Firstly, calcium metaphosphate was heated and fused onto 3mol% yttria partially stabilized zirconia plate to form an interlayer. Then a mixture of calcium metaphosphate and tetracalcium phosphate was applied on the zirconia plate, followed by heating in the presence of water vapor. Apatite and tricalcium phosphate formed on the surface of the zirconia plate by heating at 1100°C while calcium pyrophosphate and tricalcium phosphate but apatite formed above 1200°C. The products of the coated layer were discussed in relation to the reaction at the interface between zirconia plate and coated layer.
