The Modification of Titanium Dioxide MOCVD Coating in TiAlNb after Immersion in Artificial Saliva

The paper aim is to observed the modification of passive coating obtained on TiAlNb with a Metal-Organic Chemical Vapor Deposition (MOCVD) [1, 2] procedure after immersion in artificial saliva (Fusayama) with calcium content. Two temperatures [T] (400°C and 500°C), two pressures [p] (1 and 20 torr) and variable molecular fracetion [χ] from 76 to 5000 were used in MOCVD coating procedures. The X-ray spectrum confirms the dense and uniform deposition of TiO2 film on TiAlNb alloy surface. The results of analyses used in the present paper contribute of the extended research in the biomaterial domain.
