The list of 11 challenges in Table 2.1 was sufficiently comprehensive to allow the next step of analysis—identifying the corrosion grand challenges. With the challenge constructive uses of corrosion eliminated as not applicable to materials...

Corrosion grand challenge 11 entails developing a better understanding of corrosion mechanisms and morphologies, coupled with the environments in which they operate, and the fusion of the knowledge, data, models, and tools available into more accurate—and widely descriptive—models of materials and environments for all types of corrosion. 

Corrosion grand challenge IV addresses the critical need for better methods to monitor the actual deterioration of a component once it is placed in service in a corrosive environment, analyze that information, and, based on decision-making algorithms (or reasoners ), provide a reasonable forecast of the time remaining before maintenance or replacement becomes necessary. 

The topic of dissemination has been located on this report s iconic pyramid between corrosion science and the four corrosion grand challenges (CGCs) for convenience only. In fact dissemination of research results from each area of the pyramid to all of the others and to the application community is critical to the success of this endeavor.
