Aluminizing is a thermo-chemical diffusion process applied to carbon, alloy, and stainless steels; nickel-based alloys; and nickel-iron alloys to improve oxidation and corrosion resistance. When heated, aluminum vapors diffuse into the substrate to form an aluminum oxide layer at the surface, effectively creating a barrier against chemical attack. Aluminizing is particularly useful as a corrosion resistant coating for refineries and gas plants.
