G. M. Silva, A. Q. Bracarense, and M. M. A. M. Schvartzman
In pressurized water reactors (PWR), dissimilar metal welds are made to join the pressure vessels of low-alloy steel to pipes of stainless steel using Alloy 182 (UNS W86182) as a filler metal. However, it has been found that Alloy 182 is susceptible to intergranular environmentally assisted cracki ... [Corrosion 67, 076001 (2011)] published Fri Jul 01, 2011.

Modeling the Effects of Local Anodic Acidification on Stress Corrosion Cracking of Nickel

host posted on June 13, 2011 17:53
H. Hoffmeister
In the author's recent work, effects of pH, chlorides, and sulfides on local anodic acidification has been modeled by coupling electrochemical polarization and phase precipitation inside occluded cells of nickel and iron. In the present work, the model is experimentally verified and extended to de ... [Corrosion 67, 075002 (2011)] published Fri Jul 01, 2011.

Hydrogen Degradation of Cold-Drawn Wires: A Numerical Analysis of Drawing-Induced Residual Stresses and Strains

host posted on June 13, 2011 17:53
J. Toribio, M. Lorenzo, and D. Vergara et al.
Hydrogen degradation represents a problem of major technological concern in the structural integrity of prestressed concrete structures in which cold-drawn wires are the main structural component and can suffer the deleterious effect of hydrogen, with the subsequent risk of catastrophic failure. T ... [Corrosion 67, 075001 (2011)] published Fri Jul 01, 2011.

Corrosion Control of Lead in Hydrochloric Acid Solutions by N-Phenylcinnamimide and Some of Its Derivatives

host posted on June 13, 2011 17:53
E. E. Abd El Aal and S. Abd El Wanees
The corrosion inhibition of lead in 0.1 M hydrochloric acid (HCl) was investigated in the absence and presence of different concentrations of N-phenylcinnamimide (C15H13NO) and some of its p-derivatives. Weight loss, Tafel polarization, and anodic polarization under constant current (three indepen ... [Corrosion 67, 075003 (2011)] published Fri Jul 01, 2011.

Local Corrosion Behavior of Zr-1Nb Cladding in Water-Water Energetic Reactor Primary Coolants under Ambient Conditions and at High Temperature

host posted on May 26, 2011 16:27
A. Somogyi, A. Horvath, and G. Nagy et al.
Localized corrosion of the Zr-1Nb (E110) alloy was studied in solutions of a chemical composition similar to the primary coolant in Russian-type water-water energetic reactor (VVER)-type reactors. Cyclic voltammetry and chronoamperometry measurements were used to detect pit initiation, propagation ... [Corrosion 67, 066001 (2011)] published Wed Jun 01, 2011.

Role of Chloride, Sulfate, and Alkalinity on Galvanic Lead Corrosion

host posted on May 26, 2011 16:27
C. K. Nguyen, B. N. Clark, and K. R. Stone et al.
Effects of chloride, sulfate, and alkalinity on galvanic corrosion were investigated using beaker tests, lead wire electrochemical tests, and lead solder galvanic cells. At relatively high concentrations of lead and low pH values that might be present at the lead anode surface, sulfate forms preci ... [Corrosion 67, 065005 (2011)] published Wed Jun 01, 2011.

Pitting Corrosion of Co1.5CrFeNi1.5Ti0.5Mo0.1 in Chloride-Containing Nitrate Solutions

host posted on May 09, 2011 14:01
Y. L. Chou, J. W. Yeh, and H. C. Shih et al.
The purpose of this study was to investigate the effect of nitrate ions (NO3−) on the critical pitting temperature (CPT) of Co1.5CrFeNi1.5Ti0.5Mo0.1 in chloride solutions using the potentiodynamic polarization method. Results indicate that the values of CPT for the alloy in 1 (mol/L) M sodium chlo ... [Corrosion 67, 065003 (2011)] published Wed Jun 01, 2011.

R. D. Moser, P. M. Singh, and L. F. Kahn et al.
Cyclic potentiodynamic polarization (CPP) techniques were used to evaluate the influence of crevices present in stranded prestressing steels on the resistance to chloride-induced corrosion. Prestressing wire and strand specimens were exposed to simulated concrete pore solutions with chlorides adde ... [Corrosion 67, 065001 (2011)] published Wed Jun 01, 2011.

Prediction of Atmospheric Corrosion of Carbon Steel Using Artificial Neural Network Model in Local Geographical Regions

host posted on May 09, 2011 14:01
M. Halama, K. Kreislova, and J. Van Lysebettens et al.
Atmospheric corrosion of metals is a complex, nonlinear process. It involves a large number of interacting and varying factors governed by material composition, form, size, testing procedure, location of exposure, and type of application. Possible environmental factors include temperature, relativ ... [Corrosion 67, 065004 (2011)] published Wed Jun 01, 2011.
