AKSOPEEK LCF Plate–Screw Interface Micromotion Corrosion Test Long-Term Wear Stability Verified

Beyond established biological safety, long-term mechanical reliability is critical for CFR-PEEK bone plate systems.

This video presents a micromotion wear and corrosion test conducted on a representative distal femur lateral plate under simulated physiological conditions. Fetal bovine serum was used as the test lubricant to closely replicate the in vivo environment.

Key Findings:

Minimal average mass loss: 0.00226 g

Stable pH range: 6.03–6.24

Wear particle analysis compliant with ISO 17853:2011

Particles predominantly sub-micron sized

Equivalent Circular Diameter (ECD) mainly within 0.10–0.20 μm

Uniform particle morphology

No abnormal wear or corrosion observed

Overall, the results demonstrate limited wear generation and controlled particle characteristics, supporting the long-term mechanical stability of AKSOPEEK LCF in plate–screw interface applications.

For orthopedic manufacturers and medical device partners seeking advanced CFR-PEEK solutions, these findings reinforce the durability and structural reliability of AKSOPEEK LCF under sustained micromotion loading conditions.
