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.

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.

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 ...

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.

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.

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.

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.
