AFM Observations of Intergranular Corrosion of 304 Stainless Steels.

Effect of ion irradiation and implantation of H and He on the corrosion behavior of austenitic stainless steel

“…It was difficult to evaluate corrosion behavior on irradiated materials by conventional techniques such as electrochemical potential reactivation (EPR) method [14], therefore, the authors developed a new evaluation method using atomic force microscope (AFM) in previous studies [15][16][17][18]. The AFM method succeeded to obtain quantitative results relative to the corrosion behavior of ion irradiated materials.…”

Crystallographic Evaluation of Susceptibility to Intergranular Corrosion in Austenitic Stainless Steel with Various Degrees of Sensitization

“…Murr and coworkers [7,8,9,10,11,12] conducted comprehensive studies on the effects of GB misorientation, carbon content, deformation, etc., on the formation behavior of chromium carbide precipitation at GBs in austenitic stainless steel. Liu et al [13] examined the geometry of corroded grooves via AFM and discussed the relationship between the degree of sensitization (DOS) and the width and depth of the grooves. Bruemmer et al [14] investigated chromium depletion zones at GBs by energy dispersive X-ray spectroscopy in a TEM and discussed the relationship between the DOS and chromium-depleted zone size.…”
