Abstract: A large scale atmospheric corrosion monitoring test was undertaken for the purpose of characterizing environmental severity. This work was conducted at ground based Army, Navy, Coast Guard, and Air Force sites. At present over 73 sites are in operation. This work adds to the existing worldwide databases to include new military and/or related sites not previously monitored. In addition and to the extent that such data are available, relevant weather data was collected from public or military sources in order to test existing corrosion algorithms for each site. Many of the 1 year exposures have been successfully completed. However, all of the exposures currently in progress will not be completed until early 2008. Sample analyses are in progress. New data have been obtained to show the important effects of sheltering on reducing corrosion rates. Data from Daytona Beach and Tyndall AFB show that even a relatively simple open structure/sunshade can reduce corrosion rates by factors of 2 or 3. New data are being reported on corrosion vs. distance from ocean. Data were also collected for the comparison of corrosion severity among commonly used test sites and within selected sites (multiple locations within a base.)

Abstract: When the coating application does not meet the required standards, the lifetime of the coating can be substantially reduced. In the worst case, the coating may catastrophically fail immediately after being placed into service. This ongoing joint project conducted by the U.S. Navy and the U.S. Army is intended to demonstrate and provide for the automation of data collection for painting projects on critical structures and the make this data a more effective resource for making effective management decisions for the protection of DoD assets.

Abstract: Scale, corrosion and the and biological growth in industrial water handling processes result in reduced water flow though pipes, reduced heat transfer, and pump failures. Preventative treatments for these problems are based upon chemical compounds that are most often toxic and environmentally persistent. Manufacturers continue to introduce new chemicals and treatment programs onto the market, and old products have been discontinued. Many manufacturers claim that the new chemical and treatments are more environmentally friendly and safer for the plant workers and the users. The U.S. Army Engineer Research and Development Center Construction Engineering Research Laboratory has undertaken a research effort to look at these new chemical treatments. The objective of this work was to develop “green” water treatment chemicals that control biological growth, corrosion and scale while reducing or eliminating the generation of toxic substances during the manufacture, use, and disposal processes.
