Abstract
Recently the interest on the third generation bioactive glass materials is widely increasing. Doping bioactive glass-ceramic materials with various elements may inhibit or accelerate its bone bonding ability, solubility, physicochemical and osteogenic gene expression properties, stimulating bone growth and angiogenesis. In order to coating titanium substrates with thin films of bioactive materials, Pulsed Lased Deposition (PLD) technique has been used. In fact, PLD presents several important advantages with respect to the other deposition procedures, such as the congruent transfer of target composition to films, the possibility to control adherence, crystallinity, and surface roughness of the deposited. First successful results regarding the innovative RKKP glass-ceramic coatings prepared by PLD have been recently reported by us [1]. We have used a nanosecond laser source (Nd:YAG, 532nm, 10ns, 10Hz)to ablate two different bioactive material (RPB1 and RPB2). The obtained thin films have been characterized by transmission electron and scanning electron microscopies, by micro-Raman spectroscopy and X-ray diffraction. 1.J.V. Rau, R. Teghil, M. Fosca, A.
