Corrosion Initiation Projection for Reinforced Concrete Exposed to Chlorides: Part 1—Black Bars

host posted on July 20, 2011 15:11
W. H. Hartt
A protocol is described whereby time-to-corrosion, Ti, of reinforcing steel in concrete exposed to chlorides is calculated as a distributed, rather than a discrete, parameter. The method consists of inputting distribution functions for surface Cl− concentration (Cs), the effective diffusion coeffi ... [Corrosion 67, 086002 (2011)] published Mon Aug 01, 2011.

Corrosion Initiation Projection for Reinforced Concrete Exposed to Chlorides: Part 2—Corrosion-Resistant Bars

host posted on July 20, 2011 15:11
W. H. Hartt
A companion paper (Part 1) introduced a protocol whereby time-to-corrosion, Ti, of reinforcing steel in concrete exposed to chlorides is calculated as a distributed, rather than discrete, parameter. The method consists of, first, considering that identically exposed, electrochemically independent ... [Corrosion 67, 086003 (2011)] published Mon Aug 01, 2011.

Galvanic Corrosion Study in Ethylene Glycol

host posted on July 20, 2011 15:11
P. Rostron
The potential for galvanic corrosion between carbon steel and duplex (22Cr) stainless steel in impure ethylene glycol (CH2OHCH2OH) is assessed. The temperature dependence of the corrosion is determined, as well as the effect of temperature on the conductivity of dry, wet, and impure wet ethylene g ...

Cathodic Induction of Hydrogen Blistering on Carbon Steel in Alkaline Sour Environment

host posted on July 13, 2011 14:31
M. A. Domínguez-Aguilar, O. Olivares-Xometl, and N. V. Likhanova et al.
Hydrogen blistering was electrochemically induced on mild steel immersed in alkaline sour solution by cathodic reduction to study the onset of blistering. Test solution attempted to emulate that associated with water formed in catalytic cracking units of oil refinery plants with cyanide ions. Chro ...

Stress Corrosion Cracking Behavior of Alloy 182 Weld in Pressurized Water Reactor Primary Water Environment at 325°C

host posted on July 13, 2011 14:31
L. I. L. Lima, M. M. A. M. Schvartzman, and C. A. Figueiredo et al.
The weld used to connect two different metals is known as a dissimilar metal weld (DMW). In nuclear power plants, this weld is used to join stainless steel to low-alloy steel components in the nuclear pressurized water reactor (PWR). The most common weld metal is Alloy 182 (UNS W86182). Originally ... [Corrosion 67, 085004 (2011)] published Mon Aug 01, 2011.

Sour Top-of-the-Line Corrosion in the Presence of Acetic Acid

host posted on July 08, 2011 14:04
M. Singer, A. Camacho, and B. Brown et al.
Under stratified flow and dewing conditions, internal corrosion can occur at the top of horizontal pipelines where continuous injection of corrosion inhibitors does not have a mitigating effect. This research work presents an experimental study of the influence of the presence of hydrogen sulfide ... [Corrosion 67, 085003 (2011)] published Mon Aug 01, 2011.

Effect of Molybdenum on the Pitting Resistance of Co1.5CrFeNi1.5Ti0.5Mox Alloys in Chloride Solutions

host posted on June 30, 2011 13:44
Y. L. Chou, J. W. Yeh, and H. C. Shih
The effect of Mo from 25°C to 80°C on the pitting corrosion of the Co1.5CrFeNi1.5Ti0.5Mox alloys in chloride solutions was investigated. The values of critical pitting temperature (CPT) for the Mo-free alloy in 0.001, 0.01, 0.1, and 1 M sodium chloride (NaCl) are 80, 50, 30, and below 25°C, respec ...

Effect of Heat Treatment and Boron Addition on Corrosion Behavior of Ti-35Nb-7.2Zr-5.7Ta (wt%) β-Titanium Alloy in Simulated Body Fluid

host posted on June 30, 2011 13:44
P. Majumdar, S. B. Singh, and U. K. Chatterjee et al.
The corrosion behavior of Ti-35Nb-7.2Zr-5.7Ta (TNZT) and Ti-35Nb-7.2Zr-5.7Ta-0.5B (TNZTB) alloys subjected to different heat treatment conditions was investigated in Hank's solution. Depending on the heat treatment conditions, the micro-structure of the water-quenched, single-stage aged or duplex ... [Corrosion 67, 085001 (2011)] published Mon Aug 01, 2011.

Influence of Surface Treatments on the Pitting Corrosion of Type 304 Stainless Steel by Electrochemical Noise Measurements

host posted on June 29, 2011 13:43
H. S. Klapper, A. Burkert, and A. Burkert et al.
Surface treatments usually are used to modify the appearance and properties of stainless steel surfaces. Simultaneously, the corrosion resistance of the stainless steel surface being related intrinsically to the spontaneous formation of a passive layer also will be affected. In this respect, the i ...

Steel Corrosion-Inhibiting Effect of Sodium Nitrate in Simulated Concrete Pore Solutions

host posted on June 29, 2011 13:43
P. Saura, E. Zornoza, and C. Andrade et al.
When chloride-induced corrosion takes place, a local acidification occurs at the corrosion pit. Therefore, it is necessary to study the performance of corrosion inhibitors in low-pH environments. Reinforcing steel bars have been exposed to solutions that simulate the electrolytic environment of co ... [Corrosion 67, 075005 (2011)] published Fri Jul 01, 2011.
