Predictive tools for microbiologically induced corrosion via AC impedance and simulation
Advanced predictive tools to assess and mitigate microbiologically induced corrosion (MIC) in infrastructure using AC impedance and numerical simulation. This approach quantifies damage evolution and predicts performance under varied environmental and microbial conditions.
Overview
Microbiologically induced corrosion (MIC) is a significant threat to infrastructure, especially when exposed to fluctuating environmental conditions. This advanced solution leverages AC impedance measurements and numerical simulation to predict and mitigate MIC. By quantifying the impedance response of multilayer systems, this technology offers a quantitative indicator of material degradation due to microbial biofilms and environmental factors. The integration of artificial intelligence enhances the predictive model, enabling proactive measures to improve infrastructure durability and service life.
