ScholarBank@NUS Repository. https://doi.org/10.1016/j.corsci.2011.07.042 | Abstract: | AISI 416 is a high sulphur martensitic stainless steel with elliptical shaped sulphide inclusions over 2 μm in length. After laser melting the sulphide inclusions became spherical and reduced in size to below 0.5 μm in diameter. SEM investigations showed that the total number of inclusions increased dramatically and it was calculated that the total volume of sulphur in the stainless steel had not changed during the laser treatment. The pitting potential was increased by over 200. mV with an inverse linear dependency on the average inclusion size. The frequency of metastable pitting events decreased by a factor of 100. © 2011 Elsevier Ltd. | Source Title: | Corrosion Science | URI: | http://scholarbank.nus.edu.sg/handle/10635/64921 | ISSN: | 0010938X | DOI: | 10.1016/j.corsci.2011.07.042 |
