Numerical simulation of corrosion in flanges under consideration of corrosion products and their porosity
The corrosion process of flanges formed by cataphoretically coated micro-alloyed cold-rolled steel and a polymer crevice former is investigated and simulated numerically using the finite element method (FEM). Boundary conditions are determined experimentally, including the effect of corrosion products on the diffusion of diluted species through the porous medium and the reaction kinetics on the surface of magnetite (Fe3O4) as a main corrosion product. Therefore, polarization curves are measured on sintered magnetite pellets. The experimental results as well as the temperature cycle in the test climate are used as boundary conditions in the numerical simulation. Finally, good agreement between the simulation and the experiment is achieved.
期刊介绍：
Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies.
This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
