Predictive testing for microbially induced corrosion in coated materials
Developing advanced multi-parameter testing methods to simulate real-world microbial and environmental conditions, accurately predicting microbially induced corrosion in coated materials. This will help industries select more resilient materials for MIC-prone environments.
Overview
Microbially induced corrosion (MIC) poses a significant threat to critical infrastructures, affecting metals and concrete exposed to diverse microbes and environmental conditions. Current lab tests fail to fully replicate these conditions, leading to unreliable predictions of long-term material performance. This project aims to develop advanced multi-parameter testing methods that accurately simulate real-world microbial and environmental conditions to predict MIC in coated materials. By providing reliable, quantifiable data on coating performance, this research supports the development of MIC-resistant coatings and aids industries in selecting more resilient materials.
Technical specifications
The testing method involves the design of multi-parameter test chambers that replicate environmental factors such as temperature, humidity, salinity, and exposure to various microbial species. Key features include:
- Simulation of biofilm formation and microbial growth
- Introduction of material assays to measure corrosion impacts
- Accelerated testing procedures to shorten timeframes while maintaining predictive accuracy
- Data analysis and predictive model development to link MIC variables to coating degradation
Technology readiness level
Currently at TRL 3, this project has completed the initial phase of literature review and data collection on MIC mechanisms. Subsequent phases involve test chamber design and model validation, aiming to establish industry-standard testing methods for MIC-resistant coatings.
