Creation of bioactive glass coating on titanium by local laser irradiation - Part I: Optimization of the processing parameters

A focused CO2 laser beam was used to create coatings of bioactive glass on titanium substrates. Beam position remained fixed, while a computer-controlled motor stage was utilized to scan the specimens through the beam. Processing was performed in an atmosphere of air or N-2. Processing parameters, such as number of coating layers and laser power, were optimized to produce optimal results in terms of in vitro bioactivity of the coating.
