| description | Stainless steels (SSs) display striking characteristics which can nominate them as prospective candidates for an endless list of applications. These properties can be further improved by nanostructuration of the bulk material; nonetheless, scholarly attention has been diverted to surface nanocrystallization (SNC) technologies that can offer distinct advantages akin to ease of fabrication of nanocrystalline grains on the alloy surface in conjunction with enhancing overall mechanical properties. These techniques can also enable activation of the surface layer of the alloy; thus, the present paper aims to review the corrosion behavior of surface nanocrystallized (SNed) stainless steels having surface grain sizes below 100 nm. The existing technologies utilized in surface nanostructuring of SSs are examined and their respective influence on the corrosion of SNed alloy would be discussed. More importantly, several corrosion mechanisms would be suggested so as to elucidate the role of microstructure, microstrain, defect density, roughness and type of solution in the degradation of SNed SSs. In this respect, a comprehensive understanding of the impact of SNC on SSs can be achieved, which in turn paves the way for tunning corrosion resistance for future generations of SSs. |
