In the present study, the pulsed laser deposition technique was applied to coat titanium for orthopedic and dental implant applications. Iron-substituted hydroxyapatite (Fe-HAp) (0.28 wt.% of Fe) was used as coating material since titanium itself is unable to elicit biologically functional bone/material interface. The obtained Fe-HAp crystalline films are nanostructured (35 nm mean crystallite size) and possess the following characteristics: dense and compact microstructure, irregular surface with average roughness of about 0.3 m, thickness of 1.5 m and intrinsic Vickers microhardness of 17 GPa.

Abstract
In the present study, the pulsed laser deposition technique was applied to coat titanium for orthopedic and dental implant applications. Iron-substituted hydroxyapatite (Fe-HAp) (0.28 wt.% of Fe) was used as coating material since titanium itself is unable to elicit biologically functional bone/material interface. The obtained Fe-HAp crystalline films are nanostructured (35 nm mean crystallite size) and possess the following characteristics: dense and compact microstructure, irregular surface with average roughness of about 0.3 m, thickness of 1.5 m and intrinsic Vickers microhardness of 17 GPa.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
