The main purpose of this paper is to give an overview of some recent progress made in modelling of deterioration of reinforced concrete structures. The review is not claimed to be complete. It is based on some of the author’s contributions in this research area especially the papers (Thoft-Christensen 2001) and (ThoftChristensen, Svensson and Frandsen 2005). In the paper, corrosion of reinforce...

subsea structures such as manifolds, line pipes and flow lines are important investments. also because of the sensitivity of environmental issues, corrosion of these structures is of vital importance. subsea corrosion management is different from on-shore and shallow water off-shore corrosion management in mainly three factors: materials, corrosion management practice and cathodic protection. t...

In this paper, a Paris law-based model is presented whereby crack propagation occurs under cyclic loading in air (fatigue) and in an aggressive environment (corrosion-fatigue) for the case of corner cracks (with a wide range of aspect ratios in the matter of the initial cracks) in finite-thickness plates of 316L austenitic stainless steel subjected to tension, bending, or combined (tension + be...

The effects of metallurgical factors on the aqueous corrosion behavior of highentropy alloys (HEAs) are reviewed in this article. Alloying (e.g., Al and Cu) and processing (e.g., heat treatments) effects on the aqueous corrosion behavior of HEAs, including passive film formation, galvanic corrosion, and pitting corrosion, are discussed in detail. Corrosion rates of HEAs are calculated using ele...

Corrosion of steel reinforcement related to the intrusion of chloride ion is still the main threats to the durability of concrete structure, especially in marine environment. For the purpose of delaying the Cl− concentration at the surface of steel reinforcement reaching the critical value leading to initial corrosion, the permeability of concrete is usually improved by optimizing the concrete ...

Corrosion is a natural process that seeks to reduce the binding energy in metals. The end result of corrosion involves a metal atom being oxidized. Surface corrosion on aluminum aircraft skins, near joints and around fasteners, is often an indicator of buried structural corrosion and cracking In this paper we proposed a new method on which we are moving towards designing a method to detect the ...

Coatings are a cheap and efficient solution to protect underlying metallic substrates against electrochemical corrosion. High performance coatings do not only provide this protection of the substrate in the undamaged state but also when they are scratched. This enhanced protection can be achieved in many different ways (ranging from primers based on expansive phases which seal the crack upon sc...

Corrosion tests of 316L and two intermetallic compounds Fe3AI and FeCrSi in industrial Galvanizing (Zn-0.18Al), GALFAN (Zn-5AI), GALVALUME (Zn-55AI), and Aluminizing (AI-8Si) baths and lab-scale static baths were conducted. In on-line tests in industrial hot-dip baths, 316L steel shows better corrosion resistance than Fe3AI in Galvanizing, GALFAN, and GALVALUME baths. The corrosion resistance o...
