Application of aluminum diffusion coatings to mitigate the KCl‐induced high‐temperature corrosion

Pack cementation was used to produce Fe1−xAl and Fe2Al5 diffusion coatings on ferritic‐martensitic steel P91 and a Ni2Al3 diffusion coating on pure nickel. The performance of diffusion coatings against high‐temperature corrosion induced by potassium chloride (KCl) was evaluated by exposing the sampl...
