Description

Rotationally accelerated shot peening (RASP) technology was used to produce nanocrystallines and twins on the surface of 316LN stainless steel. Electrochemical corrosion experiments were carried out on the RASP-processed 316LN SS specimens in the 3.5 wt% NaCl solution. Improved passivity and better electronic properties of passive films were observed on the RASP-processed specimens. The experimental results showed that the structure with nanocrystallines and a high density of twins produced by the RASP process can provide more nucleation sites, adhesion work and homogeneous capillary force to improve the uniformity and compactness of the passive film, resulting in a better corrosion resistance.
