Corrosion Behavior of AZ Magnesium Alloys with Al and Al-11 Si Thermal Spray Coatings

host posted on February 01, 2011 00:00
A. Pardo, M. C. Merino, and R. Arrabal et al.
The corrosion behavior of AZ31, AZ80, and AZ91D Mg-Al-Zn alloys coated with aluminum and Al-11Si thermal spray was evaluated in 3.5 wt% sodium chloride (NaCl) solution at 22°C by gravimetric and electrochemical impedance spectroscopy (EIS) measurements. The corrosion products were examined using s ... [Corrosion 67, 025003 (2011)] published Tue Feb 01, 2011.

Active Protection of Fiber-Reinforced Polymer-Wrapped Reinforced Concrete Structures Against Corrosion

host posted on February 01, 2011 00:00
S. Gadve, A. Mukherjee, and S. N. Malhotra et al.
Large numbers of reinforced concrete (RC) structures that have been damaged from corrosion of steel reinforcements are rehabilitated with fiber-reinforced polymer (FRP) composites. This paper investigates active protection of the steel embedded in concrete that is treated with surface-bonded carbo ... [Corrosion 67, 025002 (2011)] published Tue Feb 01, 2011.

Corrosion Behavior of Pressure Vessel Steel Exposed to Residual Bubbles After Cavitation Bubble Collapse

host posted on February 01, 2011 00:00
H. Soyama
The corrosion potential of pressure vessel steel after exposure to residual bubbles and the open-circuit potential of Pt during cavitation were measured to investigate the corrosion behavior induced by residual bubbles after cavitation bubble collapse (as distinct from erosion caused by cavitation ...

Detecting Critical Crevice Temperature for Duplex Stainless Steels in Chloride Solutions

host posted on February 01, 2011 00:00
D. Han, Y. Jiang, and B. Deng et al.
A simple and rapid electrochemical method for the evaluation of crevice corrosion in duplex stainless steels (DSS) is described. Three types of DSS—namely, UNS S32101, UNS S31803, and UNS S32750—were tested in 1 mol/L sodium chloride (NaCl) solutions. Results showed good reproducibility with a typ ...

Effects of Environmental and Metallurgical Factors on the Stress Corrosion Cracking of Carbon Steel in Fuel-Grade Ethanol

host posted on February 01, 2011 00:00
J. A. Beavers, F. Gui, and N. Sridhar et al.
This paper presents the results of a research program to study the effects of metallurgical variables, ethanol-gasoline blends, dissolved oxygen, and inhibitors on the stress corrosion cracking (SCC) of carbon steel in ethanol. The study utilized both slow strain rate (SSR) and fatigue precracked ... [Corrosion 67, 025005 (2011)] published Tue Feb 01, 2011.

Corrosion Rate Model for 8% Chromium Cold-Work Tool Steels in Tannic Acid

host posted on February 01, 2011 00:00
H. Winkelmann and S. Ilo
Different cold-work tool steels have been treated with different heat treatments. The remaining Cr content within the matrix was calculated using thermodynamic and phase diagram calculations (for multi-component systems [TPC]). Corrosion tests were performed in tannic acid, and the corrosion rate ... [Corrosion 67, 025006 (2011)] published Tue Feb 01, 2011.

Current and Potential Distribution Modeling for Cathodic Protection of Tank Bottoms

host posted on February 01, 2011 00:00
B. Bazzoni, S. Lorenzi, and P. Marcassoli et al.
Aboveground tanks for the storage of liquid hydrocarbon are often erected with a secondary containment membrane installed below the tank bottom to prevent soil contamination in case of leakage. The design of impressed current cathodic protection in the presence of the plastic membrane is based on ... [Corrosion 67, 026001 (2011)] published Tue Feb 01, 2011.

J. Konys, W. Krauss, and N. Holstein et al.
In the helium-cooled lead-lithium (HCLL) design concept for blanket structures of a future fusion power plant, the eutectic Pb-15.7Li alloy is used as a liquid tritium breeder and is in direct contact with the structural material, e.g., ferritic-martensitic steels. Compatibility tests showed that ... [Corrosion 67, 026002 (2011)] published Tue Feb 01, 2011.

Combined Effect of Carbon Dioxide, Hydrogen Sulfide, and Acetic Acid on Bottom-of-the-Line Corrosion

host posted on January 01, 2011 00:00
M. Singer, B. Brown, and A. Camacho et al.
This research work presents a study of the combined influence of the partial pressure of hydrogen sulfide (H2S) and the concentration of free acetic acid (CH3COOH) on the general and localized carbon dioxide (CO2) corrosion at the bottom of the line. Experiments were carried out for up to 21 days ... [Corrosion 67, 015004 (2011)] published Sat Jan 01, 2011.
