Remoteness of Impressed Current Anode Groundbeds

host posted on January 01, 2011 00:00
R. P. Nagar
Selection of an electrically remote location of an anode groundbed with respect to its cathodic-protected pipeline and nearby foreign pipelines /structures is an important element of the design of impressed current cathodic protection systems. Proper understanding of commonly available and used pr ... [Corrosion 67, 016001 (2011)] published Sat Jan 01, 2011.

Effects of Sodium Chloride Concentration on Mild Steel Corrosion in Slightly Sour Environments

host posted on January 01, 2011 00:00
H. Fang, B. Brown, and S. Nes̆ić et al.
A research project was conducted to investigate the effect of a high salt concentration on corrosion from low partial pressures of hydrogen sulfide (H2S). The main objective was to study if the high concentration of chloride could initiate localized attack in this type of H2S system. Experiments w ...

Formation and Deposition of Iron Oxides on Stainless Steel and Carbon Steel in Conditions of Secondary Circuits of Pressurized Water Reactors

host posted on January 01, 2011 00:00
S. Delaunay, C. Mansour, and E. -M. Pavageau et al.
An experimental circulating water loop was built to follow the formation, the transport, and the deposition of iron oxides in the feedwater system of the secondary circuit of PWR plants. The test section was made from carbon steel while all other parts of the loop were made from stainless steel. T ... [Corrosion 67, 015003 (2011)] published Sat Jan 01, 2011.

Hydrogen Embrittlement of a Duplex Stainless Steel in Alkaline Sulfide Solution

host posted on January 01, 2011 00:00
K. R. Chasse and P. M. Singh
The hydrogen embrittlement (HE) behavior of UNS S31803 (2205) duplex stainless steel (DSS) was evaluated in alkaline sulfide solution (pH 13.3). The cathodic polarization response was evaluated using standard electrochemical techniques. Microhardness was used to measure the change in hardness upon ...

Effect of Phosphorus on the Corrosion Behavior of Carbon Steel in Sulfuric Acid

host posted on December 01, 2010 00:00
M. J. Kim, S. H. Lee, and J. G. Kim et al.
This study examined the influence of phosphorus addition on the corrosion resistance of carbon steel for a flue gas desulfurization (FGD) system using electrochemical methods, such as potentiodynamic polarization tests and electrochemical impedance spectroscopy (EIS) in 10 wt% sulfuric acid (H2SO4) ...

Localized Corrosion of Carbon Steel and Its Implications on the Mechanism and Inhibition of Stress Corrosion Cracking in Fuel-Grade Ethanol

host posted on December 01, 2010 00:00
F. Gui, N. Sridhar, and J. A. Beavers et al.
Stress corrosion cracking (SCC) of carbon steel has been observed in fuel-grade ethanol (FGE, C2H5OH). Electrochemical behavior of carbon steel and therefore the role of localized corrosion in SCC has not been studied adequately because of the difficulty in performing electrochemical experiments in ...

Adhesion Properties of Polysiloxane Topcoats

host posted on December 01, 2010 00:00
S. B. Axelsen, R. Johnsen, and O. Ø. Knudsen et al.
This paper summarizes the results from laboratory investigations of the adhesion of polysiloxane topcoats. Low adhesion together with internal stress and lack of paint film flexibility and strength are expected to be the main reasons for the cracking and flaking of protective coatings. Internal str ...

Effect of Oxygen and Heat Stable Salts on the Corrosion of Carbon Steel in MDEA-Based CO2 Capture Process

host posted on December 01, 2010 00:00
Y. -S. Choi, D. Duan, and S. Nešić et al.
The objective of the present study was to evaluate the corrosion properties of carbon steel in MDEA/H2O/CO2/O2/HSS (methyldiethanolamine/water/carbon dioxide/oxygen/heat stable salts) mixtures related to the CO2 capture process in fossil fuel-fired power plants. Short-term and long-term corrosion t ... [Corrosion 66, 125004 (2010)] published Wed Dec 01, 2010.

Inhibition of Brass Corrosion in 3% NaCl Solution by Sodium Diethyldithiocarbamate

host posted on December 01, 2010 00:00
Q. -Q. Liao, Z. -W. Yue, and Y. -J. Li et al.
Inhibition of brass corrosion by sodium diethyldithiocarbamate (DDTC) in 3% sodium chloride (NaCl) solution was investigated using the mass-loss method, electrochemical impedance spectroscopy (EIS), polarization curve method, and surface analysis method. Mass-loss results showed that the DDTC was a ... [Corrosion 66, 125002 (2010)] published Wed Dec 01, 2010.

Corrosion Behavior of Ferritic and Martensitic Power Plant Steels Under Conditions of Dual Atmospheres

host posted on December 01, 2010 00:00
D. Huenert, W. Schulz, and A. Kranzmann et al.
The most efficient construction materials for boiler water walls and superheaters in steam power plants are ferritic and martensitic steels. In practical operation, tubes are exposed simultaneously to combustion gas and air/steam on their opposite surfaces. The corrosion behavior of ferritic-marten ...
