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...

For marine platforms, assessing the structural resilience in a corroded condition is vital for both design and maintenance practices. With the development of computational and experimental methods for structural analysis, the accuracy of the structural response prediction relies on a better understanding of the material degradation process. However, a realistic estimate of corrosion is inherent...

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 atmospheres in many cities along the coastal lines in the world have been rapidly changed to coastal-industrial atmosphere. Hence, it is vital to investigate the corrosion behavior of steel exposed to this kind of environment. In this present study, Electrochemical Impedance Spectrography (EIS) and film thickness measurement were applied to monitor the corrosion behavior of weathering steel...

The relationship between dissolved oxygen (DO) and corrosion behavior of X80 steel in acidic soil simulated solution was studied by potentiodynamic polarization curves, electrochemical impedance spectroscopy (EIS), scanning Kelvin probe technique (SKP) and X-ray diffraction (XRD). Results showed that the presence of DO accelerated the cathodic process of corrosion for X80 steel in the acidic so...

Ceramic coated carbon steel coupons were corrosion tested in water with dissolved salts to simulate exposure to evaporation concentrated groundwater in an underground nuclear repository. Metallography revealed no corrosion at the ceramic metal interface of dense coatings, even though electrical measurements demonstrated that the coatings were slightly porous. Experimental results and a model to...

the effect of mentha spicata l. extract on the corrosion behaviour of carbon steel in 1.0 m hcl solution was investigated using polarization, electrochemical impedance spectroscopy (eis) and electrochemical noise (en) techniques. the solution containing 250 ppm of the ethanolic solution of extract showed the highest inhibition efficiency (ie). the effect of temperature on the rate of corrosion ...

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...

In the present paper, changes in mechanical properties of Portland cement-based mortars due to the addition of carbon nanotubes (CNT) and corrosion of embedded steel rebars in CNT cement pastes are reported. Bending strength, compression strength, porosity and density of mortars were determined and related to the CNT dosages. CNT cement paste specimens were exposed to carbonation and chloride a...
