Abstract

Improved corrosion behavior of 20%Cr-25%Ni-Nb steel resulting from a low pressure oxidation pretreatment in CO/sub 2/ has been related to changes in elemental composition and distribution in the oxide scale. Auger electron spectroscopy, secondary ion mass spectroscopy, electron microprobe, and X-ray diffraction techniques have been used to investigate the properties of the oxide scale formed on both untreated and pretreated specimens when oxidized at 823 K and 923 K in a CO/sub 2/-1%CO atmosphere. A sputter ion plating technique has been used to separate the oxide from the metal and the incorporation of chromium and silicon at the metal-oxide interface has been investigated at grain centers and grain boundaries by depth profiling. The improvement in oxide adhesion and oxidation rates, using data from Parts I and II of this study, is assessed in terms of oxide formation by solid-state displacement reactions.

Oxidation pretreatment to reduce corrosion of 20%Cr-25%Ni-Nb stainless steel. I. Weight gain and oxide thickness measurements

Journal Article Tempest, P; Wild, R - Oxid. Met.; (United States)

The improvement in corrosion resistance afforded by a low-pressure selective oxidation pretreatment on 20%Cr-25%Ni-Nb steel is assessed in terms of weight gain and oxide thickness measurements. Both can and sheet specimens were oxidized in a simulated CAGR CO/sub 2/ environment at 823, 923, and 1073 K, and gravimetric gross weight-gain measurements were supplemented by spinel and Cr/sub 2/O/sub 3/ oxide thickness measurements determined by X-ray diffractometry (XRD). The increased protection provided by the pretreatment resulted in a reduction in gross weigh gain of 3-4 times at 823 K, two and three times at 923 K, and a somewhat smaller improvementmore »« less

Investigation by fractography of the high-temperature oxidation of the 20%Cr-25%Ni-Nb stainless steel

Journal Article Desport, J; Bennett, M - Oxid. Met.; (United States)

Simple procedures have been developed for the preparation, by fracture, of transverse corroded metal sections for subsequent examination of the microstructure and microchemistry of the corrosion attack by scanning electron microscopy. Examination of 20%Cr-25%Ni-Nb (20/25/Nb) stainless steel following 120-hr oxidation in carbon dioxide at 1000/degree/C confirmed that the essentially three-dimensional picture revealed by fracture provided additional microstructural information not apparent from optical microscopy of standard metallographically mounted transverse sections. The size and morphology of the oxide grains constituting the various layers of the uniform and the pitting types of external scale were established. Nearest to the underlying steel, a bandmore »« less

The influence of a titanium nitride dispersion on the oxidation behavior of 20%Cr-25%Ni stainless steel

Journal Article Evans, H; Hilton, D - Oxid. Met.; (United States)

The oxidation behavior of 20%Cr-25%Ni stainless steels and a similar but stronger alloy containing a dispersion of titanium nitride particles has been studied over the temperature range 1023 to 1173 deg K. The dispersion-strengthened steel oxidized slightly more slowly than its dispersion-free counterpart at 1023 K, but above this temperature it was inferior in terms of gross weight gain. The parabolic growth kinetics of the chromic oxide layer in each alloy were similar, however, with an activation energy compatible with the rate-controlling step being chromium ion diffusion across the oxide. The evidence suggests that the role of the dispersed phasemore »« less

The influence of ion-implanted yttrium on the selective oxidation of chromium in Co-25 wt. % Cr

Journal Article Hou, P; Stringer, J - Oxidation of Metals; (USA)

Specimens of Co-25 wt.% Cr, Co-25 wt.% Cr-1 wt.%Y, and yttrium-implanted Co-25 wt.% Cr alloy were oxidized at 100{degree}C in 1 atm O{sub 2}. The implantation dosage ranged between 10{sup 16} to 10{sup 18} ions/cm{sup 2}. The unimplanted binary alloy oxidized to a duplex Co-rich scale, but the Y-containing ternary alloy formed a continuous Cr{sub 2}O{sub 3} layer. When the implantation dosages were lower than a nominal 10{sup 18} ions/cm{sup 2}, the alloy failed to develop a similar continuous Cr{sub 2}O{sub 3} layer as that observed with the Y-containing alloy. A temporarily stable external Cr{sub 2}O{sub 3} scale was formedmore »« less

Improvement of nonisothermal oxidation behavior of Fe and Fe-Cr alloys by superficially applied reactive oxide coatings. [Fe-6. 3%Cr, Fe-15. 9%Cr, Fe-20%Cr, Fe-25%Cr]

Journal Article Mitra, S; Roy, S; Bose, S - Oxidation of Metals; (United States)

The nonisothermal oxidation behavior of pure iron and a few iron-chromium alloys in dry air has been studied. The effects of a superficial coating of a reactive oxide, CeO{sub 2}, on the oxidation behavior were studied. Linear heating rates of 3 K/min and 6 K/min were maintained up to a final temperature ranging from 1,273-1,473 K. Coatings were applied either from a slurry or an aqueous bath. The CeO{sub 2} coating has been found to be effective not only in decreasing the nonisothermal oxidation rate but also in improving the scale adherence. Moreover, the coated samples withstood a number ofmore »« less
