LT Corrosion

Wet corrosion takes place in environments where the relative humidity is fairly high. The corrosion may cause a uniform destruction or localized destruction (pitting, stress corrosion cracking) of the metal surface. The gas turbine`s axial compressors operate in aggressive environmental conditions where low temperature corrosion phenomena, like wet corrosion, are very frequent. Aluminum based slurry coatings are widely used and approved for protection against these kinds of problems, guaranteeing an excellent galvanic protection to the blades metal.
