Aluminum - Steel Contact Considerations - Structural corrosion of aluminized steel in scale

Aug 11, 2009 · Even though aluminum is anodic to steel, you'll typically find that it's the steel that corrodes more when in contact with aluminum. The reason for this is that initial corrosion occurs first in the aluminum and forms a passivating oxide layer, then the effect reverses and the aluminum stays intact while the steel's oxide layer (rust) doesn't corrosion of aluminized steel in scaleCORROSION IN SPACECorrosion in the space environment can happen during several occasions. In satellites, manned and unmanned, the environment is present which can contribute to all kinds of corrosion.
