Oxygen tensioactive effect on molten Pb-Bi system

The knowledge of the surface properties / phenomena of liquid Pb (LL), Bi and Pb-Bi eutectic alloy (LBE) as first step to investigate the interactions between steel components (Fe, Cr, Mo, Ni) and the HLM (LL, LBE) at real reactor operating conditions (T, Atmosphere, PO2, time,..) in order to evaluate their influence on the efficiency of the system / process. The knowledge of surface properties and wetting characteristics are key requisites that make possible to study corrosion phenomena. The phenomena occuring into the liquid phase and the oxygen transfer can explain firstly the oxidation and, subsequently corrosion mechanisms
