Container Variation Testing for the Prevention of Corrosion
Abstract
AFPEA was requested to provide assistance in establishing proper packaging procedure for the B-1B Pylon. The wood crates used to ship and store the B-1B pylons were designed from combined requirements of MIL-STD-26195 and MIL-C-104 and were designed for level C packaging requirements, which indicate immediate use, within 3-6 months. However, due to the Strategic Arms Limitation Treaty, the pylons were stored in the containers for an extended period of time. As a result of this extended storage, corrosion of the cadmium-plated connector plugs occurred. This corrosion is believed to be the result of formic acid attacking the cadmium-plated parts. The formic acid formation is due to the outgassing of formaldehyde from the wood, combining with water and oxygen. The decision was made to paint the interior and exterior of the container and to add ventilation in lieu of placing the B-1B pylon inside a barrier bag. AFPEA recommended tests to identify the best possible combination of container characteristics so that future programs would not have to involve an educated guess. The results of testing show that in all cases venting the container led to a higher rate of corrosion than not venting; additionally, painting the interior of the container did lead to a much lower rate of corrosion.
