SICOM - Simulation based corrosion management for aircraft

SICOM will develop a numerical microscale model to simulate localised corrosion of Al-Alloys with regard to microstructure and the micro-electrochemical condition. It will provide corrosion rates of Al-Alloys in the mesoscale of occluded cells by means of numerical calculation as a function of physical and geometrical factors for given macro-environments. A numerical model for prediction of galvanic corrosion behaviour will be developed and up-scaled for application to structural elements of aircraft. The influence of surface treatment on modelling results will be included with regard to inhibitor release from protection systems, role of clad layer influence and oxide degrading effects. A decision support tool will be established for exploita-tion and implementation of the project results in scientific and technical applications.
