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.
Characteristics:
- Oxidation resistance
- Carburization resistance
- Hydrogen permeation
- Sulfidation resistance
Applications:
- Oil and gas tubes and pipes
- Industrial furnace components
- Catalyst trays
