- 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.
