Titanium Coating On PEEK For Medical Devices

Porous titanium coatings onto polymers are of great interest tomedical industries. A vacuum plasma spray (VPS) process has been developed to coat PEEK with a micro porous biomimetic titanium coating. This study reports the experimental characterization of the topography and microstructure and of the mechanical strength of the VPS Pure Titanium Coating on medical grade PEEK substrates. These results provide quantitative guides for the design of orthopedic implants for which such coating is used to enhance anchorage to bone tissues.
