...S. Ghosh; T. Ramgopal The effects of chloride and phosphoric acid (H₃PO₄) on the corrosion of Alloy C-276 (UNS N10276), UNS N08028, and UNS N08367 have been studied using electrochemical techniques. All of these alloys are widely used in the chemical process industries because...

...L. Wang; G.-J. Yin; Q.-F. Zhang; J.-X. Pu Weight loss and polarization studies showed that 2-mercaptobenzoxazole is effective for the inhibition of low-carbon steel over a wide concentration range of aqueous phosphoric acid (H₃PO₄) solutions. The inhibitor retards the anodic...

...), and scanning electron microscopy (SEM) were used to study seven combinations of surface treatments on Al 2024-T3 (UNS A92024). It was found that phosphoric acid (H₃PO₄) treatment greatly affected the concentration of copper at the alloy surface. It also was found that polishing and acid...

...E. Khamis; M. A. Ameer; N. M. AlAndis; G. Al-Senani Corrosion inhibition of steel in phosphoric acid (H₃PO₄) by thiosemicarbazide derivatives was studied using different chemical and electrochemical techniques. Protection efficiency up to 99% was obtained with small amounts...

...A. Guenbour; S. Zeggaf; A. Ben Bachir; M.L. Escudero; M.F. Lopez The inhibiting effects of two mineral compounds on corrosion of nickel in phosphoric acid (H₃PO₄) polluted by sulfide ions (S^2–) was studied using electrochemical and spectroscopic techniques...

...G.A. El-Mahdy; S.S. Mahmoud Effects of sulfuric acid (H₂SO₄), phosphoric acid (H₃PO₄), nitric acid (HNO₃), and hydrochloric acid (HCl) on kinetics of the formation and dissolution behavior of zirconium oxide (ZrO₂) were studied using...

...S. El Hajjaji; L. Aries; N. Pebere; F. Dabosi; J.-P. Audouard; A. Ben Bachir The passive state behavior of the ferritic Z1 CD 29-4 stainless steel (SS) in industrial phosphoric acid (40 wt% H₃PO₄ with 1,000 ppm chloride [Cl^–] and 330 ppm sulfate...

...A. Bellaouchou; A. Guenbour; A. Benbachir The effect of sulfide (S^2–) ions on the corrosion behavior of an austenitic steel (Uranus B6) in phosphoric acid (H₃PO₄) solutions was examined. The critical concentration at which the effect of S^2– ions became...

...K. Mitsuda; H. Shiota; T. Murahashi Carbon corrosion in a phosphoric acid fuel cell (PAFC) was experimentally simulated by causing hydrogen starvation or by intentionally introducing defects (e.g., local removal of specific components) into the cell. In some cases, significant carbon corrosion...

...A.K. Agrawal; J.E. Alter; A.R. Hamilton, II; J.E. Beavers The cracking behavior of a Cu-2Mn weld alloy in concentrated phosphoric acid-alcohol solutions in the temperature range 249 to 304°C has been investigated using the slow strain rate test technique. Moderate amounts of air ingress...
