Abstract: There is provided a surface alloyed component which comprises a base alloy with a diffusion barrier layer enriched in silicon and chromium being provided adjacent thereto. An enrichment pool layer is created adjacent said diffusion barrier and contains silicon and chromium and optionally titanium or aluminum. A reactive gas treatment may be used to generate a replenishable protective scale on the outermost surface of said component.
