Abstract
30 keV N 2 +, Ti + and N 2 + followed by Ti + ions were implanted at room temperature on plain and sensitized 304 stainless steel (304 SS) foils. The ion fluences ranged from 1 × 10 17 ions/cm 2 to 5 × 10 17 ions/cm 2. Pitting studies in quiescent non-dearated 3.5 wt.% NaCl electrolyte and Electrolytic Potentiokinetic Reactivation (EPR) studies in a standard electrolyte of KSCN + H 2SO 4 were carried out on plain, sensitized and implanted plain, and sensitized 304 SS foils. In general, the localized corrosion behaviour deteriorated on implantation in plain 304 SS irrespective of the nature of the implant species and their fluences employed in this work. However, the localized corrosion behaviour of implanted sensitized 304 SS showed an improvement. The benefits accrued was dependent on the nature of the implant species and their fluences. An attempt has been made to explain why the implant species interact differently, with the consequent difference in the localized corrosion behaviour, when the stainless steel substrate is in the sensitized state.
