Abstract

The growth of titanium oxide layer on titanium surface by the micro-arc oxidation technique was investigated. Ca(CH₃COO)₂ (0.3M), Na₂CO₃ (0.6M) and Na₂HPO₄ (0.1M) solutions were employed as electrolytes. SEM and EDS microanalysis were used for morphology, composition characterization and low-angle X-ray diffraction to describe titanium oxide crystallographic orientation. TiO₂ films formed by using 0.3M Ca(CH₃COO)₂ and 0.1M Na₂HPO₄ solutions showed a porous, homogeneous surface structure, with presence of phosphorous and after an hydrothermical treatment using a Ca(OH)₂ suspension during 24h at 60ºC was observed phosphorous and calcium.
