Abstract

Crystalline Calcium Phosphate-TiO2 nanostructured porous layers were fabricated via micro arc oxidation technique under different times to investigate how growth time effects on morphology, topography, phase structure, and chemical composition of the layers. Considering the SEM and AFM observations, the layers showed a porous morphology with a rough surface where the pores size increased with time. The highest porosity and roughness was achieved at intermediate times. XRD technique revealed that the layers consisted of α-Tri Calcium Phosphate (α-TCP), hydroxyapatite (HAp), anatase, and calcium titanate phases. It was observed that the HAp relative content reached its maximum value at intermediate times. It was found that the HAp phase gradually forms over a TiO2 inner layer during the MAO growth. Based on XRD patterns, the α-TCP and HAp crystalline sizes were determined as ~32.4 and ~27.7 nm, respectively.
