VL - 34 IS - Extra SE - Articles DO - 10.3989/revmetalm.1998.v34.iExtra.722 UR - https://revistademetalurgia.revistas.csic.es/index.php/revistademetalurgia/article/view/722 SP - 118-121 AB - The influence of silicon incorporated into the alloy by means of ion implantation of 1 x 10<sup>15</sup> ions/cm<sup>2</sup> at 150 keV on the protective scale development based upon Cr<sub>1,3</sub>Fe<sub>0,7</sub>O<sub>3</sub> and manganese-enriched spinels, Mn<sub>1,5</sub>Cr<sub>1,5</sub>O<sub>4</sub> after oxidation of an austenitic AISI 304 stainless steel at 1,173 K and atmospheric pressure of air for 144 h has been studied. The presence of small quantities of silicon at the outermost layers of the alloy promotes transport of chromium during the early stages of oxidation. Further, ion implantation seems to play a beneficial role against decarburization of the alloy. ER -
