摘要
ZrO2-HAp-TiO2 porous layers were fabricated by micro arc oxidation/electrophoretic deposition hybrid processes in the electrolytes consisted of beta-glycerophosphate, calcium acetate, sodium phosphate, and yttria-stabilized zirconia within short times and only in one step. The layers had a porous structure with a pores size of 50-750 nm. They contained anatase, hydroxyapatite, monoclinic ZrO2, tetragonal ZrO2, and some minor phases with a varying fraction depending on time. Increasing the time, the tetragonal ZrO2 transformed to monoclinic ZrO2. Moreover, hydroxyapatite relative content decreased with time. The nanosized zirconia particles (d = 20-40 nm) were dispersed on the surface and in the layers depth. (C) 2010 Elsevier B.V. All rights reserved.
