Abstract

$BaTiO_3$ coatings were prepared by micro arc oxidation (MAO) method. Only $Ba(OH)_2$ was dissolved in the electrolyte and process time was less than 30 min. Commercial purity $Ba(OH)_2$ (97%) containing $BaCO_3$ as impurity was used in preparing the electrolyte. XRD showed that the coating was composed of largely $BaTiO_3$, and in some process conditions, small quantity of impurity, $BaCO_3$, was characterized in the coating layer. The quantity of $BaCO_3$ could be controlled to negligible quantity by regulating the applied voltage and duration time of the MAO process.
