摘要:
A method for protecting a surface of an article from sulfate corrosion resulting from exposure to a sulfate containing material at an elevated temperature includes coating the surface with a nickel based material to form an anti-corrosion coating. The nickel based material includes NiO, a spinel of formulation AB 2 O 4 , or a combination thereof, wherein A includes nickel, and B includes iron or a combination of manganese and a B site dopant.
