Atmospheric corrosion occurs when metallic structures are exposed to humid air forming a thin electrolyte film in the range of up to a few hundred micrometers. The model presented here accounts for charge transport as well mass transport involving 10 species and 6 homogeneous ... Mehr lesen
An established method for benchmarking the atmospheric corrosion resistance of materials is the use of accelerated corrosion tests (ACT) performed in climate chambers. The main purpose of the ACTs is to make reliable and fast predictions of the long time behavior. The tests expose ... Mehr lesen
This example models cathodic protection of a steel reinforcing bar in concrete. Three different electrochemical reactions are considered on the steel surface. Charge and oxygen transport are modeled in the concrete domain, where the electrolyte conductivity and oxygen diffusivity depend ... Mehr lesen
Galvanic corrosion between two different phases (alpha and beta phases) in a metallic (magnesium) alloy is simulated for a representative cross-sectional microstructure configuration. A key feature in the model formulation is the implementation of both anodic and cathodic regions at ... Mehr lesen
This model exemplifies how the rate of steel corrosion in an oil platform increases over time due to build-up of a resistive film on the sacrificial anodes, formed by reaction products. The model also includes secondary current distribution electrode kinetics on the protected steel ... Mehr lesen
The model simulates atmospheric corrosion of a galvanic couple, comprising of an Al-Co-Ce metallic coating and an aluminum alloy, which is in contact with electrolyte film of 100 micrometer thickness. The corrosion inhibitors are released from the metallic coating and are transported ... Mehr lesen
Digital Rock technology utilizes high-resolution imaging techniques, such as SEM and X-ray CT, to characterize the pore structures of rock cores. This approach enables pore-scale modeling of reservoir rocks, offering valuable insights into pore morphology, connectivity, and fluid ... Mehr lesen
This tutorial shows how to use the Optimization interface to perform electrode kinetics parameter estimations based on polarization data. A zero-dimensional electrode polarization model is defined that separates kinetics expressions for the metal dissolution and the oxygen reduction ... Mehr lesen
The use of Aluminum (Al) isolator is a commonly employed mitigation strategy for galvanic corrosion between magnesium alloy (Mg) and mild steel (MS). The present model demonstrates the effect of Al isolator thickness on galvanic corrosion severity using a parametric study. The electrode ... Mehr lesen
The impressed current cathodic protection (ICCP) system is often employed to mitigate corrosion of buried pipelines in the oil and gas industry. Metallic objects such as buried pipelines, which are present within the current flow of the ICCP system, may suffer from the stray current ... Mehr lesen
