Abstract

For oxide coatings, prepared by applying plasma electrolytic oxidation (PEO) to aluminium alloy Al6082, this conference contribution presents the finite element (FE) microstructural modeling of the PEO coatings. By utilizing the coating phase maps, obtained by electron back-scattered diffraction (EBSD) technique, the corresponding images have been converted into FE models with a detailed microstructure representation. By utilizing experimental data such as loading-unloading curves obtained upon micro-indentation using a Berkovich tip on the coatings cross-sections and surfaces, the material models representing the coating constituent phases have been calibrated.
