Initial corrosion observed on the atomic scale

Nature, 2006
Corrosion destroys more than three per cent of the world's GDP. Recently, the electrochemical decomposition of metal alloys has been more productively harnessed to produce porous materials with diverse technological potential. High-resolution insight into structure formation during electrocorrosion is a prerequisite for an atomistic understanding and ...

Initial Studies of Plutonium Corrosion

Journal of Nuclear Science and Technology, 2002
We report here our preliminary results of pliitonium corrosion studied using photoelectron spectroscopy and secondary ion mass spectrometry. Plutonium surfaces were cleaned by Ar ion bombardment, and examined using X-ray and ultraviolet photoelectron spectroscopy, Auger electron spectroscopy and secondary ion mass spectrometry. Curve fitting procedures

A model for prediction of time from corrosion initiation to corrosion cracking

Cement and Concrete Composites, 2007
Abstract Prediction of time to corrosion cracking is a key element in evaluating the service life of corroded reinforced concrete (RC) structures. This paper presents a mathematical model that predicts the time from corrosion initiation to corrosion cracking.

Effect of corrosion inhibitors on the initiation of chloride‐induced corrosion on reinforced concrete structures

Materials and Corrosion, 2008
AbstractCorrosion of carbon steel rebars is the main cause of failure of reinforced concrete structures. To prevent and delay the occurrence of corrosion, a high quality concrete with a proper cover and a good mixture proportion should be designed.

Hydrogen-Induced Initiation of Corrosion in Aluminum

The Journal of Physical Chemistry C, 2007
Corrosion resistance of aluminum alloys is related to the presence of a thin, passivating aluminum oxide film on the surface. In this paper, we perform first-principles quantum-mechanical calculations to provide atomic scale understanding of the initiation of corrosion in Al.

Modelling corrosion initiation of steel in concrete

Proceedings of the Institution of Civil Engineers - Construction Materials, 2007
The main cause of corrosion initiation in steel reinforcement within concrete is the presence of chlorides above a threshold value. The primary source of chlorides is from the external environment, either from marine structures or de-icing salts. The most commonly used method of predicting or modelling chloride ingress is to use Fick's second law ...

Localized corrosion and crack initiation

Materials Science and Engineering: A, 1988
Abstract Consideration is given to the initiation of stress corrosion cracks at metal surfaces where structural features, such as grain boundaries or slip steps, emerge, as well as to initiation from pits, crevices or other geometrical discontinuities, in the context of a variety of metal-environment systems.

Initiation of stress-corrosion cracking in metals

Metals Technology, 1982
AbstractTwo factors that have been found to have an important influence on stresscorrosion crack initiation, in certain cases, are the extent of environmental access and the presence of residual surface stresses. These are discussed, and examples from service are cited where such effects have played a major role.
