Abstract

We report on the successful deposition by PLD method of three biomaterials, hydroxiapatite doped with zirconia (ZrO2: HA), β-tricalcium phosphate (β-TCP) and bioglass (BG57), onto titanium substrates, for medical applications. The deposited implants have been investigated morphologically by Scanning Electron Microscopy, coupled with Energy Dispersive X-Ray Spectroscopy (EDS). The surface morphology of the implants presented roughness values very close to the ones defining the histological structure of bone. EDS spectra evidenced the absence of impurities in the deposited films. This study demonstrated that, at microscopic level, the morphology of BG57 thin films presented a superior quality as compared with ZrO2:HA and β-TCP ones, emphasizing their capacity to cover the metallic implants, in form of thin films, making them suitable for applications in implantology..
