Supporting corrosion control efforts across equipment lifecycles
Corrosion destroys equipment, decreasing readiness and reliability while causing
safety hazards and increasing maintenance and other ownership costs. The Department
of Defense (DoD) estimates corrosion costs the department over $23 billion annually.
In addition, the U.S. Army attributes more than 50 aircraft accidents and 12 fatalities
to corrosion since 1985.* Concurrent Technologies Corporation (CTC) is working to
support corrosion control efforts across the equipment lifecycle–from design and
materials selection through operation and maintenance.
Since 2000, CTC has been performing a wide variety of corrosion services for government
and commercial clients.

Why Work with CTC?
Whether you need to estimate component service life, compare materials performance,
or determine the condition of your materials, CTC can find the solution that’s right
We can collect and analyze data, equipment, materials, and environments to characterize
and understand corrosion problems. We can then test, evaluate, demonstrate, and
validate the most appropriate and cost-effective prevention and control solutions–saving
you time and money.
CTC offers deep experience and capabilities:
CTC uses the following equipment:
- Extensive experience with laboratory development and fabrication of NDI corrosion
reference standards for DoD engineering applications
- Capability to design, fabricate, and install custom test equipment and nonstandard
test and analysis protocols per client specifications.
- Auto Technology 40 cu.ft. cyclic corrosion chamber, capable of more than 50 different
pre-programmed corrosion tests, including those specified in ASTM B117, SAE J2334
- Q-Fog cyclic corrosion chamber
- Atlas Weatherometer
- Q-Panel Q-Sun accelerated weathering xenon arc weatherometers that simulate the
entire spectrum of sunlight with capabilities of varying the irradiance, temperature,
humidity, water spray, and exposure duration.
- Q-Panel QUV apparatus that simulates the ultraviolet (UV) portion of the sunlight
spectrum, in which the most damaging effects of sunlight to coatings exposed outdoors
- Gamry PCI4/300 potentiostat/galvanostat/zero resistance ammeter capable of DC corrosion
and AC electrochemical impedance spectroscopy (EIS) testing for modeling corrosion
behavior, and measuring corrosion rates, pitting potentials, polarization resistance,
and corrosion potential.
- Portable nondestructive inspection (NDI) systems for assessment and evaluation of
hidden corrosion under paint, as well as damage/defects within composite structures
CTC has been engaged in evaluating and addressing aluminum sensitization issues,
including subsequent stress corrosion cracking, on Navy ships since 2010. CTC has
focused on the design, development, demonstration, and transition of repair strategies
and technologies that reduce costs and improve readiness. Our solutions involve:
- Mitigation for un-cracked sensitized aluminum
- Mitigation for cracked sensitized aluminum
- Prevention using coatings
- Prevention using new materials
Our technologies optimize demonstrated solutions, including friction stir welding,
coatings, and reverse sensitization units, which Navy stakeholders have identified
as potential solutions.
