Researchers at the National Institute of Standards and Technology have developed a noninvasive technique utilizing terahertz radiation that reveals corrosion in concrete-encased steel before it can cause any significant degradation of the structure.
A joint project by The University of Akron and Airborne Maintenance and Engineering Services is targeting “cold spray” repair of corroded and worn parts on commercial aircraft.
This investigation used an analysis with the Auger electron spectroscopy technique to characterize the corrosion in a microelectronic component utilized to activate automobile airbags.
Airmen with the 19th Maintenance Squadron at the Little Rock Air Force Base in Arkansas are using nondestructive inspections to identify potential cracks in a variety of aircraft parts.
Plastic packaging films can be readily impregnated with vapor-phase corrosion inhibitors (VCIs) to provide corrosion protection, in addition to the basic physical barrier afforded by the plastic.
