Pulsed laser ablation and deposition of bioactive glass as coating material for biomedical applications

A study of the laser ablation and deposition, on Ti–Al substrates, of a biologically active glass Bioglassw. suitable for bone implants is reported. The analysis of the gaseous phase by emission spectroscopy and the characterisation of the films from a compositional and morphological point of view have been carried out. The mean chemical composition of the deposits obtained from Bioglass ablation is very close to the target composition and the morphology indicates that different mechanisms of material ejection are present. q1999 Elsevier Science B.V.
