Corrosion behaviour of molybdenum-implanted stainless steel

Finite Volume model for diffusion- and activation-controlled pitting corrosion of stainless steel

“…(19) or (21), respectively (depending on the mode of dissolution control), and the pit solution's boundary to the bulk solution (with zero metal ion concentration, see Fig. 2) is marked by a lacy cover (as observed in foil electrode experiments [18,36]), allowing for free flow through the holes on P lacy; J : cðx; tÞ ¼ 0; Jðx; tÞ -0 ð24Þ but not through the solid parts in between on P lacy;c : Jðx; tÞ ¼ 0; cðx; tÞ -0: In the present case, the ionic concentration at the electrode boundary is spatially discontinuous, which is noteworthy from a computational point of view. Use of the (classical) Finite Element Method for solving Eq.…”

“…Thus, the diffusion-driven concentration drop in S eb ¼ S eb;sat , obtained from evaluation of Eq. (36), is compensated by refilling S eb;sat from S solid;diss . If activation-controlled dissolution prevails, S solid;diss dissolves according to the dissolution flux defined in Eq.…”

Overview of Surface Modification Strategies for Improving the Properties of Metastable Austenitic Stainless Steels

“…Ion implantation is a process of surface modification of metals, which is frequently applied to stainless steels. Implanting ions on austenitic stainless steel causes changes in microstructure, including defects, phases, and staining [138,139]. Several works have been conducted on structural austenitic stainless steels using intermediate carbon and nitrogen atoms to induce microstructural changes and, consequently, enhance their mechanical properties [140,141].…”
