| Abstract: |
A study on the thermal spray deposition of polymer onto metals-based structures is presented. The present study reports the novel results of microstructural, Crystallization, Friction and Mechanical Properties of dense and as well as highly porous Polyetheretherketone (PEEK) coating. A new kind of approach is proposed for manufacturing of highly porous PEEK coating on a dense PEEK coating for orthopedic implants and successfully fabricated porous PEEK coating by means of thermal spray process. To imitate the structure of natural bone, as-sprayed top PEEK coating has porosity of more than 60% vol. and pore sizes of 30-80 ¼m. Mechanical results of dense PEEK coating show that PEEK coating exhibited good strength, hardness (20 HV0.1) and good bonding strength (15 MPa) with the metal substrate. Thermal sprayed porous PEEK coating that can be used for future implants instead of plasma sprayed titanium coating on dense PEEK implants because porous PEEK improves the bone-implant interface joining compared to plasma-sprayed titanium coating on PEEK.
This study aims to report the new developments and contributions to research on the thermal spray metallization of polymer-based materials, which has gained recent attention for potential and novel applications.
