National Corrosion and Materials Reliability Lab
Through research, education and training, the National Corrosion and Materials Reliability Lab (NCMRL) provides solutions to the corrosion needs of industry and government in order to maximize asset life, production efficiency and worker safety. The goal is to preserve and extend the integrity of the structures, such as buildings, bridges, pipelines, roads, ports and off-shore platforms that can be continuously occupied and operational during the entire design life of current or new civil infrastructures. The NCMRL conducts state-of-the-art research, development, testing and assessment of corrosion-resistant materials, corrosion mitigation strategies, corrosion sensors and asset life prediction tools.
- Development, testing and assessment of corrosion-resistant materials, corrosion mitigation strategies, corrosion sensors and asset life prediction tools.
- Combining basic research with investigations focused on specific technical problems in materials degradation, durability, reliability, and integrity.
- Atmospheric corrosion: perform standard and custom experiments simulating extreme weathering conditions and is used to test coating systems as well concrete. Equipped with 2 Fog chamber LF 8151 QS Model test chambers, which can be instrumented for electrochemical evaluation.
- Coating system evaluation and testing: equipped with state-of-the-art electrochemical instrumentation capable of measuring the extreme small currents typically found in coating system evaluation.
- General corrosion severity evaluation to characterize the materials response to corrosive environments reproduced in laboratory conditions.
- Extreme service conditions materials selection: study corrosion mechanisms and materials performance in extreme service conditions such as supercritical CO2, environments containing H2S, high pressure and temperature exposure conditions. The NCMRL is certified to work with H2S and the equipment and instrumentation allows to evaluate high pressure and temperature conditions.
