Development of Bioactive Alumina-Wollastonite Composite by Electrophoretic Deposition
Alumina is excellent biomaterial and used in hip prostheses, dental implants and so on. Wollastonite particles were deposited in pores of porous alumina by electrophoretic deposition and an alumina-wollastonite composite was produced. Apatite was formed both inside the pores and on the surface of the composite of the alumina-wollastonite composite by soaking in a simulated body fluid. It was indicated that the deposited wollastonite particles induced the apatite formation. Novel composite material with both excellent mechanical properties and high bioactivity was developed.
