Development of new corrosion monitoring methods, precise corrosion measurement instrumentation, and superior performing coatings contribute to an increased understanding of the complexity involved in the corrosion process. The US Army is in search of lightweight structural alloys with superior corrosion resistance and a synergistic effort between ASL computing and experimental materials research is advancing the development of this technology. Most lightweight alloys are prone to corrosion and require periodic replacement and regular maintenance, thereby adding to operational costs. ASL is providing a corrosion and alloy-design framework for faster development and testing of material solutions in realistic application environments.
Highlights of ASL’s novel approach include:
- An atoms-to-grains model for alloys linked to corrosion lifetime
- Finite element analysis linked to corrosion vulnerability and testing of possible failure models
- Linking the mechanical and chemical environments to the fundamental aspects of alloy design
- Providing computational tools to reduce the number of ASTM tests needed for corrosion testing
- Surface treatments to significantly reduce corrosion in Mg-based alloys
