Modeling pitting corrosion by means of a 3D discrete stochastic model Universiteit Gent
Investigation of the effect of pitting corrosion on the fatigue strength degradation of structural steel using a short crack model Universiteit Gent
Steel support structures of offshore wind turbines (jackets and monopiles) undergo both fatigue and corrosion damage, impacting their lifetime. This paper investigates how pitting corrosion, caused by being exposed to the marine environment, affects the fatigue strength of structural steel. A short fatigue crack model is used to estimate the minimum required applied load amplitude which causes a growing crack emanating from the bottom of a ...
Modeling localized aluminum alloy corrosion in chloride solutions under non-equilibrium conditions: Steps toward understanding pitting initiation Vrije Universiteit Brussel
A multi ion transport and reaction model has been developed with the intent to improve via simulation the understanding of the first steps of localized corrosion (pitting) of aluminum alloys at the microscale. However, the onset of pitting could not be predicted, but the simulation of all parts of a micropolarization curve, excluding the pitting regime, was possible. Unlike previous models, the model does not use the assumption that the system ...
DFT study on the mechanism of inclusion-induced initial pitting corrosion of Al-Ti-Ca complex deoxidized steel with Ce treatment KU Leuven
© 2019 The mechanism of inclusion-induced initial pitting corrosion of Al-Ti-Ca complex deoxidized steel with Ce treatment was studied by the experimental investigation and theoretical calculation. To figure out which phases of complex inclusion containing different components induced initial pitting corrosion, the scanning electron microscope (SEM) analysis, the continuous immersion experiments and density functional theory (DFT) calculation ...
Employing electrochemical frequency modulation for pitting corrosion KU Leuven
By using the electrochemical frequency modulation (EFM) technique, the non-linear behavior of a corroding system is measured. This non-linear behavior is likely to be different for a system undergoing uniform or pitting corrosion. The implementation of the EFM technique to detect pitting corrosion has been investigated by observing the fluctuations in the so-called causality factors. These causality factors, resulting from an EFM test and in the ...
Pitting and General Corrosion Susceptibilities of Materials for High Level Radioactive Waste (HLW) Disposal KU Leuven
The disposal of high-level radioactive waste (HLW) in deep stable geological formations is accepted at an international level to be the most promising option for its long-term management. The supercontainer concept is currently being considered as the Belgian reference design, wherein the waste will be stored in geological stable clay formations. The outer barrier of the supercontainer is the envelope, which should be made of a ...
Effect of heat treatment on the microstructure and pitting corrosion behavior of 316L stainless steel fabricated by different additive manufacturing methods (L-PBF versus L-DED): Comparative investigation exploring the role of microstructural features on KU Leuven Vrije Universiteit Brussel
Numerical study on the effect of pitting corrosion on the fatigue strength degradation of offshore wind turbine substructures using a short crack model Universiteit Gent
Steel support structures of offshore wind turbines (jackets and monopiles) undergo both fatigue and corrosion damage, impacting their lifetime. Due to the time‐variant uncertainties associated with environmental and mechanical loads, having reliable models that allow to predict the degradation due to corrosion and fatigue is necessary to accurately assess the structural integrity and to support decision making. Three Belgian universities (UGent, ...
Cutting the Gordian Knot of electrodeposition via controlled cathodic corrosion enabling the production of supported metal nanoparticles below 5 nm Universiteit Antwerpen
In the past decades, there has been an ongoing search for tailor-made active metal nanoparticles for the use as electrocatalysts. An upcoming versatile and green method for the synthesis of nanoparticles is electrodeposition. However, the state-of-the-art electrodeposited metal particle sizes are in the range of 50200 nm. Production of high surface area metallic electrocatalysts with small particle sizes is a serious limitation of ...
