“…The substrate material used in the present study was a grade AISI 316L austenitic stainless steel (SS) with the nominal chemical composition (in wt%): 17 Austenitic steel specimens, provided by ArcelorMittal-Imphy, were polished on SiC paper up to the 800 polishing grade, then washed with ethanol and finally dried just before isothermal oxidation at 800°C.…”

“…Moreover, other studies show that titanium coatings [11][12][13][14] or laser surface modification can be applied on AISI 316L materials for improved tribological properties [15,16]. After oxidation at 900°C, X-ray diffractograms [17] seem to show the presence of NiFe 2 O 4 , Fe 2 O 3 and/or (Fe 0.6 Cr 0.4 ) 2 O 3 . Depending on the application, such materials are subjected to corrosive atmospheres and thermal cycling.…”

In situ X-ray diffraction was used to identify the oxides formed on the AISI 316L (containing 2% Mo) stainless steel during isothermal oxidation at 800°C, in air. Good oxidation behavior was observed on this steel when considering kinetics, structural characteristics and scale adherence. It was demonstrated that molybdenum plays a protective role in that it hinders the outward iron diffusion and leads to the lower growth rate and the better scale adherence. The oxide scale was then composed of Cr 2 O 3 with a small amount of Mn 1,5 Cr 1,5 O 4 at the external interface. Pre-oxidation of the AISI 316L also improved its aqueous corrosion resistance. No pitting corrosion occured during the corrosion test. Aqueous corrosion testing also showed that the oxide scale formed at 800°C is crack-free and still adherent after cooling to room temperature.

“…Several studies proposed that, at high temperature, chromia-forming alloys such as AISI 316L SS exhibit an oxide growth leading mainly to Cr 2 O 3 and Mn 1.5 Cr 1.5 O 4 formation [9][10][11]. It has also been demonstrated that yttria addition leads to an increased oxidation resistance at 800°C [12].…”

-Water vapour mixed with air (10 vol.% H 2 O) has little effect on the AISI 316L stainless steel oxidation under isothermal conditions at 800 and 900 °C. The oxide scale is composed of Cr 2 O 3 and Mn 1.5 Cr 1.5 O 4 located at the external interface. Results show that the presence of water lowers the specimen's mass gain. At 1000 °C, the effect of water vapour on the scale structure is deleterious. In situ X-ray diffraction permits to show that the breakaway is due to iron oxidation starting after about 30 hours. This leads to an external Fe 2 O 3 scale growth and an internal multilayered FeCr 2 O 4 scale formation.

“…The existing bibliography to date on the behavior of porous metals at high temperatures is limited, although in previous investigations, exclusively focused on PM stainless steels, it is quite clear that the presence of pores affects the amount of oxides formed [18]. Porosity greatly increases the real area of metal exposed to attack, with which the mass gain per unit of the apparent surface increases dramatically [19][20][21]. Moreover, it favors formation of less-protective oxides than those formed under the same testing conditions in steels with the same composition, but that are less porous [20][21][22][23].…”

This paper covers a study on the oxidation behavior in air of four materials processed by means of powder metallurgy (PM), in such a manner that their porosity will be high and so they can be used to manufacture anodic supports in solid-oxide fuel cells (SOFC). For this, powders with a Fe base (AISI 430L and Fe22Cr grades) and with Ni base (Ni20Cr and Ni625 grades) have been processed through a novel method specifically designed for this type of applications. The oxidation kinetics of the four materials has been studied during their exposure to high temperature, and the oxides formed both inside and on the samples have been characterized. The protective abilities of the oxides formed depend on the chromium losses during sintering of the outer surface, the oxygen diffusion rate during hightemperature exposure and the irregularities on the morphology caused by the processing method. The results of these studies have allowed to reach the conclusion that, from amongst the materials tested, Fe22Cr exhibits the best behavior in air at 800°C.
