Corrosion of reinforcement is one of the main durability problems of concrete structures. The corrosion induces several structural damages which affect the serviceability and the safety of concrete structures. The structural risk is promoting the possibility of embeded sensors which could give alerts in order to repair the structure before reaching dangerous levels of damage. There are an incre...

The repair and rectification of corrosion damage continues to be a major factor in the life cycle costs of aircraft. The present approach to corrosion control is based on ‘Find-and-fix’. Once an area of corrosion is found, rectification is carried out as soon as possible. This often involves the blending away of corrosion damage and the re-protection of the blended area. Where the depth of corr...

This paper reviews the progress in atmospheric corrosion of zinc since 2009. It firstly summarises the state of the art in 2009, then outlines progress since 2009, and then looks at the significance of this progress and the areas the need more research. Within this framework, it looks at climate effects, oxide formation, oxide properties, pitting, laboratory duplication of atmospheric corrosion...

Iron released by steel corrosion was found to be a key impurity in reactions with dissolved oxygen in liquid lead-bismuth eutectic alloys. The iron-oxygen-magnetite equilibrium was characterized, allowing the quantification of phenomena that are important for long-term operation of lead-alloy based installations such as corrosion rate control and management of precipitates.

Localized corrosion of Cu and Al thin films exposed to aqueous NaCl solutions was studied using liquid cell transmission electron microscopy (LCTEM). We demonstrate that potentiostatic control can be used to initiate pitting and that local compositional changes, due to focused ion beam implantation of Au(+) ions, can modify the corrosion susceptibility of Al films.

Recent advancements in metal fibers have introduced a promising new type of stainless steel fiber with high stiffness, high failure strain, and a thickness < 100 μm (<0.00394 in.) that can be utilized in a steel fiber-reinforced polymer. However, stainless steel is known to be susceptible to pitting corrosion. The main goal of this study is to compare the impact of corrosion on the mechanical p...

The continuous search for better corrosion inhibitors, due to vast differences in the media encountered in industry remains a focal point in corrosion control. The use of organic compounds to inhibit corrosion has assumed great significance due to their application in preventing corrosion under various corrosive environments. These compounds have great potential to inhibit aqueous corrosion due...

The purpose of this study was to investigate the effects of 316L stainless steel (SS) corrosion products on the in vitro biomineralization process, because tissue necrosis, bone loss, impaired bone mineralization, and loosening of orthopedic implants are associated with ions and debris resulting from biodegradation. Rat bone marrow cells were cultured in experimental conditions that favored the...

Fourteen thermotolerant and thermophilic bacterial isolates from a hot spring in Guanajuato State, Mexico, were tested for their ability to induce the corrosion of carbon steel in monocultures and, in selected cases, in mixed cultures and co-culture with a sulfate-reducing strain, SRB-M. Characterization by 16S rDNA showed that three of the thermophilic isolates (G9a, G9c, and G11) belong to th...
