Abstract

Thin films of biocompatible materials such as hydroxylapatite (HA) - Ca₁₀ (PO₄)₆(OH)₂ were deposited by laser ablation technique. The films of HA were created on Ti substrates by KrF laser. The layers were deposited in vacuum, in pure H₂O vapors (pressure 2 X 10^-3 mbar - 2 X 10^-1 mbar), and in Ar/H₂O vapor mixture. Influence of laser energy density E_T (3 Jcm^-2, 13 Jcm^-2) and substrate temperature T_g (500 degree(s)C - 760 degree(s)C) on the film parameters was studied. Two different technological processes were used for HA target preparation. Films and targets were characterized by Rutherford backscattering analysis (RBS), particle induced x-ray emission (PIXE), x-ray diffraction (XRD), scanning electron microscopy (SEM) and by Knoop microhardness and scratch test. The best crystalline HA films were reached in the mixture of Ar/H₂O. Higher T_g had to be used for such deposition. Higher T_g was also preferable from the point of film microhardness. Adhesion of films to the substrates in the range of tens of Newtons was measured. The preliminary results of in vitro experiments of films biotolerance and resorbability are also presented.
