Effect of Buffer Capacity on Electrochemical Corrosion Behavior of Alloy 800 in Sulfate Solutions

host posted on January 01, 2012 00:00

T. Nickchi and A. Alfantazi
Electrochemical corrosion behavior of Alloy 800 (UNS N08800) in sulfate solution was compared in the presence and absence of potassium phosphate monobasic/sodium hydroxide (KH2PO4/NaOH) buffering reagent. Cathodic polarization, cyclic voltammetry, and electrochemical impedance spectroscopy were us ... [Corrosion 68, 015003 (2012)] published Sun Jan 01, 2012.

S. Xiong, Z. Zhu, and H. Zhang et al.
This study investigates the influence and mechanism of SO42− ions on the pitting corrosion of boiler water-wall tubes. The kinetics of SO42− ions on pitting corrosion was assessed by mass gain rate and depth gain. Sample surfaces were examined using transmission reflection metallurgical microscopy ...

M. Momeni, A. Ale-yassin, and M. H. Moayed
In this study, a new solution based on hydrochloric acid (HCl) and sodium thiosulfate (Na2S2O3) has been developed for detecting and measuring degree of sensitization (DOS) using the double-loop electrochemical potentiodynamic reactivation (DL-EPR) method. Two types of stainless steels including T ... [Corrosion 68, 015007 (2012)] published Sun Jan 01, 2012.

Evaluation of the Susceptibility of a Superduplex Stainless Steel Welded Joint to Sulfide Stress Corrosion by Slow Strain Rate Tensile Tests in Sour Solutions

host posted on January 01, 2012 00:00

V. G. Silva, S. S. M. Tavares, and I. P. Baptista et al.
The usage of superduplex stainless steels in offshore petroleum production has increased considerably in the last years. Particularly, the use as flowline pipes for oil production needs careful research on the effect of critical environmental conditions on the stress corrosion resistance of welded ...

H. S. Klapper, R. Baessler, and K. Weidauer et al.
In the last years, geothermal power has become a reliable and significant energy source. Because service conditions in geothermal facilities from deeply located aquifers are usually critical in terms of corrosion, materials selection is a very important issue. Preliminary evaluation of the materia ... [Corrosion 68, 016001 (2012)] published Sun Jan 01, 2012.

S. Thomas, N. Birbilis, and M. S. Venkatraman et al.
Anodic and cathodic polarization of zinc was carried out in 0.1 M sodium chloride (NaCl) solution with pH ranging from 1 to 13. The electrochemical data was then contrast to thermodynamic chemical equilibrium diagrams. The analysis shows that, in general, variations in corrosion of zinc with pH ar ...
