In the KorSikA project, developing a deeper understanding of corrosion conditions, effects and influences has improved methods and processes that prevent corrosion.
The knowledge expected from this project should sustainably increase the efficiency and operational reliability of energy technology plants and enable a significant extension of their service life. In the project, test concepts for the "corrosivity" (susceptibility to chemical decomposition) of the new filler materials were also developed for the first time. Based on the understanding and knowledge gained, test procedures were defined on the basis of electrochemical measurement and analysis methods, which make it possible to carry out far-reaching material qualification, also with a view to the expected areas of application. From this, concepts for corrosion protection could be derived. In order to obtain a deeper understanding of the corrosion reaction of the sintered pastes, a possible influence of the manufacturing processes with regard to introduced impurities or carry-over was analyzed in order to develop suitable remedial measures if necessary. Here, the central objective was the prevention of corrosive degradation, and the evaluation of the mobility properties of residues by ionic conductivities has been a central part of the investigations.
