<p>A method for coating steel and other metals in which a metallic material layer of at least one of Si, Ge, Cr, W, Mo, Ta, Nb, Ni, and Zr is deposited onto a metal substrate. The metallic material layer is then annealed so as to form a diffusion layer between the metallic protective coating and the metal substrate. Thereafter, the metallic material layer is passivated, forming a stable composition of at least one of carbides, borides, nitrides, silicides, oxides, and mixtures thereof on the metallic protective coating. The protective coatings of this invention significantly reduce the corrosion rate of steels and other metals used in bromide-based absorption cycles.</p> |
