The Influence of Surface Treatment on the Diffusivity in the Surface Layers of Stainless Steels
It is well known that the rate of oxidation of stainless steels in steam at temperatures higher than about 400° C depends on the surface treatment of the material [1–4]. Ground specimens oxidize slower than electropolished or pickled ones although the effect at temperatures higher than about 700° C is of short duration. It has been suggested [1–4] that the lower oxidation rate of ground specimens is due to an increased diffusivity of the alloy components in the deformed surface layer giving a thicker and more protective chromium oxide.
