The project deals with the preparation of composite passivation multilayers, the analysis of their
physico-chemical properties and their interaction with lower class steel and modified with a
cementitious binder based on CEM I. Emphasis will be placed on adhesion properties and
mechanical and chemical stability in the aggressive environment inside reinforced concrete
structures. The used cement binders will be purposefully modified to achieve a lower pH.
Passivation multilayers based on inorganic cluster molecules and metal oxides will be prepared
by a combination of dip-coating and advanced plasma-chemical methods, especially with the
use of high-power pulse magnetron sputtering and discharge in a hollow cathode. The
knowledge gained can be used in the area of anti-corrosion protection of concrete steel, or for
the targeted treatment of the surfaces of lower grade steels.
