| Abstract Scope |
Corrosion in metallic implants poses significant risks, including device malfunction, inflammatory tissue responses, and the release of harmful metal ions, underscoring the critical need for early detection. Very small amplitude (5-10 mV) sinusoidal voltage can be used to monitor corrosion of pacemakers, orthopedic devices, and dental implants. The technique is non-invasive in nature and can be used to monitor metal ion release and surface degradation as a function of time. Although much research, including by our research group, is reported in the literature, modeling of the corrosion phenomena using the low-voltage sinusoidal voltages typically lacks in that it does not appropriately take into account the double-layer capacitance formation due to metal ion adsorption on metal, biofilm formation, and the resistance offered by the body fluids.
This research is an investigation of detailed physical models that accurately relate to corrosion of bioimplants to monitor and prevent acceleration of corrosion. |
