The paper aims at the synthesis and characterization of a wollastonite ceramic layer (belonging to the CaO-SiO₂ system) deposited by PLD (pulsed laser deposition) method on a titanium metal substrate, in order to improve titanium biocompatibility and bioactivity. The silicate precursor mixture was synthesized by the sol–gel method. From this precursor was obtained the ceramic target by sintering at 1150 °C for 6 h. The obtained films on the titanium metal substrate were characterized by x-ray diffraction, scanning microscopy and by determination of the contact angle. Also, the materials were tested in vitro to determine the bioactivity and biocompatibility of thin films. The obtained results indicate the presence of wollastonite in films composition and a good bioactivity in the presence of cells, which suggests that this type of thin films is suitable for medical implants.
