Abstract: Ferrous metal articles, such as stainless steel articles, characterized by at least one brazed joint, in which the braze is a non-ferrous alloy are aluminized by first selectively coating the braze alloy with an aluminide-forming metal, such as nickel, and then thermally diffusing aluminum over the entire surface of the article including the selectively coated braze, such that a sacrificial corrosion resistant coating is produced wherein the aluminum coating on the ferrous metal surface is characterized by the presence of iron aluminide, and wherein the aluminum coating on the metal-coated braze is characterized by the presence of metal aluminide, such as nickel aluminide. The aluminide coatings are further enhanced by the application of a non-metallic coating, e.g., a conversion coating.
