Summary Composition, structure and energy distribution of electrons in thin
metal oxide films play a key role in electrochemical processes at metal /
metallic oxide / electrolyte phase boundaries. Many scientific papers
have dealt with this topic, but information on the effect of some
alloying elements on growth, stability and electrochemical properties of
oxide films as well as the possibility of its corrosion protection is
Due to wide application and economic importance of aluminium, copper and
nickel alloys, increasing attention has been turned to their protection
from corrosion. However, a great number of commercial inhibitors used
to that purpose is toxic, so that efforts have been recently made to
replace them by natural, non-toxic substances.
Results of previous research show that specific compounds isolated from
plant material (rosemary leaves) are very effective corrosion
inhibitors. In the project proposed, special attention will be given to
microbiologically influenced corrosion (MIC) in seawater. The presence
and metabolic activity of microorganisms on metallic surfaces (Al,
CuNi10Fe) can lead to changes in oxygen concentration and pH value,
which in turn affect the type of corrosion attack and its intensity. On
the other hand, metabolic products of some microbiological species can
act as "a brake" for the corrosion process.
The results of studies proposed will contribute to understanding of the
justification of application of materials proposed in the wide range of
application, mainly as construction materials, as active materials in
protector protection and in fuel cell development.
The results of studies proposed will be published in international
journals and refered presented at congresses.
We expect these studies to contribute to modification of surface layers
and to protection of materials and of the environment, providing an
incentive to economic development.
