Abstract or Summary
  • The corrosion behaviors of carbon and stainless steels were investigated in supercritical CO₂ (sCO₂ ) containing H₂O and O₂ simulating conditions that exist in direct sCO₂ power cycle heat exchangers. Thermodynamic properties of CO₂-H₂O-O₂ systems related to the corrosion phenomena were determined using NIST software. The exposure tests of the corrosion samples were performed at a pressure of 80 bar and two temperatures, 50 and 250 °C up to 1500 hours. The samples were exposed to H₂O-containing CO₂ and sCO₂-containing H₂O both with and without O₂. The corrosion tendency of the alloys was compared using mass change measurements. The surface microstructure and composition of the corrosion films were investigated using X-ray diffraction and scanning electron microscopy. The overall results indicate that the corrosion mechanism for each material in H₂O containing sCO₂ is different from the mechanism in sCO₂ containing H₂O and that the mechanisms for corrosion are different with the introduction of O₂.

  • description.provenance : Rejected by Julie Kurtz(julie.kurtz@oregonstate.edu), reason: Hi Lucas, Rejecting for the following reasons - 1) Abstract page - is missing your major - Materials Science. The first line should read - Lucas Teeter for the degree of Master of Science in Materials Science presented on ... 2) The Copyright page appears after the Title page, so move it to appear after the abstract and before the title page. 3) The headings in the pretext pages should be all caps, and bolding is not permitted. So change the heads for - TABLE OF CONTENTS, LIST OF FIGURES, and LIST OF TABLES and remove all bold. It's fine to use bolding in the actual thesis. Everything else looks good. Once revised, log back into ScholarsArchive and go to the upload page. Replace the attached file with the revised PDF and resubmit. Thanks, Julie on 2016-12-19T17:19:23Z (GMT)
