Microstructure and properties of composite polyetheretherketone/Bioglass® coatings deposited on Ti-6Al-7Nb alloy for medical applications

► Composite coatings consist of Bioglass® particles embedded in a PEEK matrix. ► Coatings are micro-porous, the volumetric porosity is 28%. ► Diffusion of Na from the glass to the PEEK matrix after heat-treatment. ► EPD is very useful to deposit porous PEEK/Bioglass® coatings on titanium alloy.
