Survey Furthers Development of Corrosion Software Prediction Technology
NAVAIR and Aircraft Makers Express Need for More Sophisticated Tools
Corrosion impacts the safety, function, and readiness of military assets, costing the Department of Defense $22.5 billion each year, according to the DoD Corrosion Policy and Oversight Office. Specifically, for Navy and Marine Corps aviation, this totals $2.6 billion and results in an average of 25 days of corrosion-related non-availability per year for each aircraft on active status.
Corrosion is clearly an enemy for which we need better weapons, since it is estimated that 35 percent of corrosion costs can be avoided by implementing better up-front analysis and design.
The corrosion engineer is at a disadvantage when compared to his colleagues in structures and aerodynamics who have access to powerful FEA (Finite Element Analysis) software tools that can predict structural loading and flight response on complex 3-D computational models. As soon as weapons systems are deployed, material characteristics change due to environmental effects. Consequently, coatings and paint systems will degrade and get damaged, but the corrosion engineer does not have a tool to assess the long-term effects of these forms of degradation on the aircraft materials.

DoD Releases Guide on Alternatives to Hex Chrome
In September 2012 the Department of Defense released a new guide for weapons systems program managers to assist them in choosing alternatives to hexavalent chromium (CrVI), known colloquially as hex chrome. The DoD Corrosion Policy and Oversight Office developed the guide with assistance from the DoD Corrosion Prevention and Control Integrated Product Team, comprising materials experts from across the military departments, AMMTIAC, and LMI Government Consulting. (See New Tool Helps DoD Weigh Hex Chrome Alternatives.)
The guide is titled Analysis of Alternatives to Hexavalent Chromium: A Program Management Guide to Minimize CrVI Use (Spiral 1). It has been released to the public and can be downloaded in pdf format from the report title link above. Read More ...
Department of Defense Major Corrosion Events:
The Way Ahead
Presidential initiatives have been underway in 2012 to enhance efficiency in spending within the federal government. In keeping with this focus on cost-consciousness, Frank Kendall, Under Secretary of Defense for Acquisition, Technology, and Logistics, issued a memo on June 7, which directs agencies under his purview to review their involvement in conferences that cost more than $100,000.
Although the Corrosion Policy and Oversight Office remains alert to ongoing changes in the procedures required to follow the guidance contained within Mr. Kendall's memo and other federal directives, the Corrosion Office recognizes that, under the law, the mission of the DoD corrosion community of experts must continue and remain a critical DoD focal point.

"Corrosion: The Silent Menace"
2013 Exhibit Unlocks the Mysteries of Degradation for the Next Generation
The forces that drive the breakdown of infrastructure can be complex enough for corrosion scientists to apprehend. But for non-experts, the factors that cause steel bridges to collapse or fighter jet airframes to crack are even harder to grasp.
To help prevent catastrophic failures like the collapse of the I-35 West Bridge over the Mississippi River in Minneapolis, the next generation needs to know more.
Understanding the forces underlying the breakdown of bridges, pipelines, and waterways requires a direct experience with the science underlying such mysteries. The DoD Corrosion Policy and Oversight Office will spotlight the natural phenomena that lead to corrosion and material degradation in a novel exhibit aimed at the next generation of infrastructure preservationists.
