Accelerated progress in corrosion research is anticipated as a result of the stunning ongoing increase in the ability to tailor composition and structure from the nanoscale to the mesoscale; to experimentally probe materials at finer levels of spatial resolution as well as the dynamics of chemical reactions; and to model computationally intensive problems that unravel the nature of these reactions and the response of materials to the environment. Corrosion science today is presented with unprecedented opportunities to advance fundamental understanding of environmental reactions and effects from the atomic and molecular levels to the macro level.

do not at present incorporate corrosion factors. Great opportunities exist to use the framework of these materials design and engineering tools to stimulate corrosion research and development to achieve quantitative life prediction, to incorporate state-of-the art sensing approaches into experimentation and materials architectures, and to introduce environmental degradation factors into these capabilities.

From page 3... ...
The most effective routes to corrosion mitigation rely on knowledge of the underlying mechanisms causing the corrosion. This alone would justify increased attention to the science base of corrosion research; however, understanding corrosion processes would also be beneficial for improving critical technologies such as batteries and fuel cells, semiconductors, and biodegradable materials.

design tools used to identify the best, most cost-effective options and to guide the selection of materials and corro sion-mitigation techniques. To support this vision corrosion research should focus on addressing significant gaps in corrosion knowledge so that the results can be applied directly to sectors that are significantly affected by corrosion damage.

: CGC I: Development of cost-effective, environment-friendly, corrosionresistant materials and coatings; CGC II: High-fidelity modeling for the prediction of corrosion degradation in actual service environments; CGC III: Accelerated corrosion testing under controlled laboratory conditions that quantitatively correlates with the long-term behavior observed in service environments; and CGC IV: Accurate forecasting of remaining service time until major repair, replacement, or overhaul becomes necessary -- i.e., corrosion prognosis. The CGCs have been expressed as engineering and technology challenges, and these are deemed to be the drivers and guiding principles of the framework for prioritizing efforts.

To facilitate the rapid dissemination of results, the committee encourages the involvement of industry in the planning and execution of the research and technology development. Recommendation: Using as guidance the four corrosion grand challenges developed by the committee, each federal agency or department should iden tify the areas of corrosion research pertinent to its mission and draw up a road map for fulfilling its related responsibilities.

CGC III: Accelerated corrosion testing under controlled laboratory conditions that quantitatively correlates to long-term behavior observed in service environments. • Smart accelerated corrosion testing that accurately predicts performance under a range of exposures, ensuring durability, and early detection of unforeseen corrosion-related failure mechanisms.

The descriptions reveal that advances across many scientific disciplines will be needed to close current technological gaps, and they clarify the need for a balanced program of traditional single-investigator and multi-investigator efforts that will bring corrosion researchers into collaborative groups that include experts in characterization and computational modeling. Recommendation: Funding agencies should design programs to stimulate single-investigator and collaborative team efforts and underwrite the costs of realistic test laboratories open to the corrosion community and its collabora tors, including industry researchers.

Actions by the individual agencies are critical to this proposed national strategy, but the variety of materials applications and the broad commonality of the underlying science research suggest that collaboration across agency boundaries will add significant value.
