Corrosion Behavior of Modified UNS N08367 Austenitic Steel in Supercritical Water

host posted on September 01, 2010 03:33 Article Rating
Y. Yang, Q. Yan, and R. Ma et al.
The corrosion behavior of a modified UNS N08367 austenitic steel (mod. UNS N08367) exposed to deaerated supercritical water at 650°C and 25 MPa for exposure times to 1,000 h was investigated using weight gain measurement and oxide structure analysis. The morphologies, microstructures, and chemical ... [Corrosion 66, 096002 (2010)] published Wed Sep 01, 2010.

Electrochemical Noise Monitoring of the Cathodic Protection of Mg-Rich Primers

host posted on July 31, 2010 00:16
K. N. Allahar, Q. Su, and G. P. Bierwagen et al.
Mg-rich primers provide cathodic protection of aluminum substrates similar to that provided by Zn-rich primers for steel substrates. This protection is due to the mixed potential that develops between the more active Mg particles in the binder and the aluminum substrate. Monitoring the open-circuit ...

Protocol for Projecting Time-to-Corrosion of Reinforcing Steel in Concrete Exposed to Chlorides

host posted on July 31, 2010 00:16
W. H. Hartt
A protocol is described whereby time-to-corrosion, Ti, of reinforcing steel in concrete exposed to chlorides was calculated as a distributed, rather than discrete, parameter. The method consists of inputting (1) an average value for surface [Cl−] and the effective diffusion coefficient, (2) the mea ... [Corrosion 66, 086002 (2010)] published Sun Aug 01, 2010.

Corrosion Behavior of Cr-Mn-Ni Stainless Steel in Acetic Acid Solution

host posted on July 31, 2010 00:16
V. Shankar Rao and L. K. Singhal
Corrosion behavior of a Cr-Mn-Ni stainless steel designated as J204 (DIN 1.4376) was evaluated in acetic acid (CH3COOH) solutions by electrochemical methods and boiling immersion tests. Resistance to stress corrosion cracking (SCC) was evaluated using U-bend and slow strain rate tests (SSRT). The i ... [Corrosion 66, 085004 (2010)] published Sun Aug 01, 2010.

Literature Review of Commercially Available Alloys That Have Potential as Low-Cost, Corrosion-Resistant Concrete Reinforcement

host posted on July 31, 2010 00:16
F. Presuel-Moreno, J. R. Scully, and S. R. Sharp et al.
A literature review was conducted with the goal of identifying alternative, low-cost, corrosion-resistant steel reinforcement materials. The most promising alternate reinforcing materials seen to date that are less expensive than 300 series stainless steels include low-Ni austenitic stainless steel ...

2009 Frank Newman Speller Award Lecture: Prevention and Control of Corrosion in Aircraft Components—Changes over Four Decades

host posted on July 31, 2010 00:16
B. Hinton
The author has been involved in corrosion prevention and control for Australian Defence Force (ADF, Canberra, Australia) aircraft and helicopters for more than 40 years. During those years, polymeric and conversion coatings and plated metallic layers have been the major technologies used for preven ... [Corrosion 66, 085001 (2010)] published Sun Aug 01, 2010.

Effects of Sodium Fluoride on Structure and Corrosion Resistance of Plasma Electrolytic Oxidation Ceramic Coatings on Magnesium Alloys

host posted on July 31, 2010 00:16
Z. P. Yao, X. R. Liu, and L. L. Li et al.
F− is used widely as an additive in the electrolyte solutions during the plasma electrolytic oxidation (PEO) of Mg alloys. The goal of this work was to investigate effects of sodium fluoride (NaF) on the structure and corrosion resistance of the ceramic coatings containing Ca and P on AZ91D (UNS M1 ...

Development of an Electrochemical in Situ Detection Sensor for Grounding Grid Corrosion

host posted on June 22, 2010 20:10
X. -L. Zhang, X. -H. Zhao, and Y. -G. Wang et al.
An electrochemical in situ detection sensor for grounding grid corrosion was developed. Because the auxiliary electrode used to polarize the working electrode was encapsulated into an insulation cavity (carbon steel), the polarization current was made to flow through the pinhole to the working elec ...

Influence of Nitrate on Pit Stability in Austenitic Stainless Steel

host posted on June 22, 2010 20:10
R. S. Lillard, G. Vasquez, and D. F. Bahr et al.
Sufficiently high concentrations of nitrate (NO3−) additions to chloride (Cl−) solution resulted in the elimination of slow rise metastable pitting transients and, correspondingly, localized corrosion inhibition in Type 304L (UNS S30403) stainless steel (SS). In comparison, the nucleation frequency ... [Corrosion 66 075004 (2010)] published Thu Jul 01, 2010.

Real-Time Monitoring of a United States Air Force Topcoat/Mg-Rich Primer System in ASTM B117 Exposure by Embedded Electrodes

host posted on June 22, 2010 20:10
K. N. Allahar, D. Wang, and D. Battocchi et al.
The protection of metallic structures by organic coatings has traditionally been as a barrier, reducing the transport of water, ions, and oxygen from the environment to the substrate. Organic coatings are also used as repositories for corrosion inhibitors, which passivate the substrate, and metalli ... [Corrosion 66 075003 (2010)] published Thu Jul 01, 2010.
