Methods and properties of PEEK-based composite coatings.
| S. No. | Coatings | Deposition Method | Significance | Ref. |
|---|---|---|---|---|
| 1 | PEEK coating on Ti alloy (Ti-13Nb-13Zr) | Electrophoretic deposition (EPD) | Excellent wear resistance Very good adhesion Low frictional coefficients |
[136] |
| 2 | HAp/PEEK composite coating on PEEK substrate | Cold Spray coating | Better biocompatibility and osseointgration for clinical applications | [149] |
| 3 | SiC/PEEK composite coating on SS | electrostatic spray coating method | Scratch resistance Hardness increases |
[150] |
| 4 | h-BN/bioactive glass/PEEK coating on SS 316L | Electrophoretic deposition (EPD) | Good adhesion strength Wetting behavior |
[137] |
| 5 | PEEK/HAp on 316L SS | Electrophoretic deposition (EPD) | Good antibacterial activity | [151] |
| 6 | PEEK coating on Ti implant | Thermal spraying | Improved stability and fracture resistance Abrasion resistance |
[152] |
| 7 | PEEK/ Bioglass composite coating on PEEK substrates | Cold gas spray | Better wear resistance Biomechanical performance |
[143] |
| 8 | ZrO2/PEEK coating on Ti6Al4V substrates | Thermal spraying | Improved wettability Blood compatibility Great potential for medical applications |
[153] |
| 9 | Al2O3/PEEK, SiO2/PEEK coatings on Ti6Al4V substrates |
Thermal spraying | High hardness Optimum tribological properties Potential candidate for bearing material |
