Abstract:
A method of providing sulfidation corrosion resistance and corrosion induced fouling resistance to a heat transfer component surface includes providing a silicon containing steel composition including an alloy and a Si-partitioned non-metallic film formed on a surface of the alloy. The alloy is formed from the composition η, θ,and τ, in which η is a metal selected from the group consisting of Fe, Ni, Co, and mixtures thereof, θ is Si, and τ is at least one alloying element selected from the group consisting of Cr, Al, Mn, Ti, Zr, Hf, V, Nb, Ta, Mo, W, Sc, La, Y, Ce, Ru, Rh, Ir, Pd, Pt, Cu, Ag, Au, Ga, Ge, As, In, Sn, Sb, Pb, B, C, N, P, O, S and mixtures thereof. The Si-partitioned non-metallic film comprises at least one of sulfide, oxysulfide and mixtures thereof.
