Porous TPS layer on implant made of PEEK

TPS Coating on PEEK


This TPS coating is applied in a vacuum and achieves a high level of porosity combined with good and adequate coating adhesion. This technique makes coating bioinert plastics with a biocompatible and bone attractive surface possible.
TPS-coated PEEK component
Range of Application
  • Orthopaedic implants and implant components made from PEEK
Advantages of the Procedure
  • Surface enlargement without thermal microstructural changes to the implant material
  • Improved fatigue strength of the implants compared with sintering techniques
  • Increased purity and adhesive strength compared with other methods (e.g. APS Atmospheric Plasma Spray)


Properties of the PEEK material will not be modified by the TPS coating.

  • Color: gray
  • Coating thickness: 50-250 µm
  • Roughness Ra: 20-40 µm
  • Porosity: 20-60 %
  • Adhesion strength: ≥ 22 MPa
  • Biocompatible
