Abstract

The influence of silicon incorporated into the alloy by means of ion implantation of 1 x 10¹⁵ ions/cm² at 150 keV on the protective scale development based upon Cr_1,3Fe_0,7O₃ and manganese-enriched spinels, Mn_1,5Cr_1,5O₄ 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.
