Adhesion improvement and in vitro characterisation of 45S5 bioactive glass coatings obtained by atmospheric plasma spraying

Plasma sprayed bioactive glass coatings were studied using crushed 45S5 powder. It is widely accepted that plasma coating microstructure highly affected by the characteristics of powder and parameters set on spraying process. Once deposition was optimized, two strategies carried out to analyse their effect adhesion: cooling with carbon dioxide while a post heat treatment as-sprayed coatings. Scanning electron microscopy X-ray diffraction used for obtained Additionally, adhesion substrate degradation in Tris buffer solution evaluated different samples studied. Coatings have been tested vitro evaluate response immersion simulated body fluid, Hank's Balanced Salt Solution. The results show an increase strength treated due stress relaxation achieved above transition temperature. Moreover, bioactivity test apatite layer at surface produced all
