TESTING EVALUATION AND
TECHNICAL ADVISORY
Aerofin Laboratories can evaluate samples that have been exposed to high temperatures for core diffusion into the cladding.
Corrosion protection in the form of cladding is susceptible to core diffusion into cladding during heat treatment processes. At high temperatures the solubility of copper and magnesium is enough to generate the risk of these elements diffusing from the core into the cladding.
Diffusion of these elements into the cladding reduces the electrochemical potential between the cladding and the core, such that the cladding no longer acts as protection against corrosion.
