Abstract:

La détérioration d'une structure en béton peut être dû à de nombreux processus, qui agissent individuellement ou en synergie. Quelques exemples de processus qui causent la détérioration des matériaux cimentaires comprennent des attaques sulfatique, des cycles gel-dégel, de la carbonation ou des attaques salins provoquant la corrosion des armatures dans le béton. La corrosion des armatures est l'un des phénomènes les plus importants qui réduit la durée de vie des ouvrages en béton, en impactant de façon importante le budget maintenance de la structure affectée.

Abstract:

<p>Ultramonit is a system under development for permanent installation on critical parts of the subsea oil- and gas pipelines in order to monitor the corrosion continuously by using ultrasound. The communication link which connects the Ultramonit units with the outside world is identified as the systems bottleneck, and it is thus of interest to compress the ultrasonic data before transmission. The main goal of this diploma work has been to implement and optimize a lossy compression scheme in C on the available hardware (HW) with respect to a self-defined fidelity measure.

Abstract:

In this work, a comparative electrochemical study has been performed to evaluate corrosion inhibition property of several film-forming corrosion inhibitors provide by Akzo Nobel on carbon steel in a chloride solution. For carbon steel exposed to 1 M NaCl solution with and without added inhibitor, electrochemical measurements including electrochemical impedance spectroscopy (EIS), linear polarization resistance (LPR) at different exposure time intervals, and potentiodynamic polarization at the termination of the exposure, have been performed to investigate the film forming process and to evalua

Abstract:

Corrosion within the oil and gas sector is an ongoing concern for operators. The challenging nature of extraction and processing fluids is an unavoidable cause of severe metallic corrosion. With modern emphasis on health, safety and the environment, the case for managing corrosion has become an imperative agenda. Whilst new and more effective methods of mitigation are key, an interim solution is improving the value of current methods. A literature survey carried out within this project has revealed CO2 corrosion as contributing to most corrosion related failures within the industry. The corros

Metallic additives, also known as anticorrosive pigments, can provide sacrificial cathodic protection and complement the barrier protection afforded by heterogeneous organic coatings to metallic substrates. The unique systematic study of the corrosion resistance of an epoxy coating reinforced with different sizes (80nm, 500nm, 10um) and continuous multiple pigment volume concentration (0, 2%, 10%, 20%, 45%) below global critical pigment volume concentration of zinc particles were studied.

Abstract:

Modern high-strength but environmentally friendly, fuel-efficient and weight-optimized designs vital to the aeronautical and transport industries have resulted in the multi-material concept in which a wide range of materials are employed to exploit the various desirable mechanical and physical properties. These multi-material design concepts are susceptible to corrosion as the chemical and electrochemical properties of their constituent materials can vary widely. Since current corrosion mitigation strategies are not focused on these multi-material systems, there is an urgent need to understand

Abstract:

Reinforced concrete (RC) structures comprise a large part of the structures and infrastructures around the world. Most of them have been built in the first half of the 20th-century, so their service life is currently at a critical stage from the maintenance perspective. One of the most frequent and expensive degradation mechanisms they present is associated with the reinforcement corrosion. This research is focused on the carbonation-induced corrosion considering that it is the primary degradation cause of RC structures in Paraguay.

Proprietary mixtures of amines and carboxylic acids are used as volatile corrosion inhibitors (VCIs) for the protection of steel and iron components against atmospheric corrosion during storage and transportation. Interactions between amines and carboxylic acids have been comprehensively reported in the literature. However, little is known about the nature of the vapours these mixtures emit. The present study focused on the development of the evolved gas analysis method which will help in the characterisation of the vapours released by VCIs.
