Summary: Corrosion influences the service life of building
materialsand accordingly the service life of whole structures. In order
toavoid corrosion activity it is necessary to separate thestructures from
the aggressive environment. It is very importantto consider the materials,
structure functions, environment andadequate protection against corrosion.
The investigation has been made to develop a comprehensiveCorrosion
Prevention Method-Expert System (ES CPM), to establishthe condition of
corrosion protection on structures during theirservice life. New types of
assessment have been proposed tocreate a uniform assessment of corrosion
protection onstructures, and an optimum procedure has been developed for
itsmaintenance.
An expert system has also been developed to select acorrosion
protection system during erection of steel structuresand their service
life.
Keywords: Corrosion, expert system, protection, assesment, prevention.

Summary: A quantitative comparison of some well known methods
for
estimating corrosion parameters, corrosion current density, corrosion
potential, anodic and cathodic Tafel coefficients and polarization
resistance, is presented. Direct methods of Barnartt (3 point), Jankowski
and Juchniewicz (4 point), LeRoy, Cao Chu-nan and Bandy, the iterative
multi- point methods of Green and Gandhi (BETACRUNCH), Mansfeld (CORFIT,
POLCURR), Jensen and Britz (LLSM) and the other methods of Štern (CORRPAR),
Feliu and Feliu have been considered. The comparison is based on
experimental data obtained with a system ARMCO-Fe in 1 mol dm-3 sulfuric
acid. Potentiostatic technique was used.
The results have shown that direct methods are useful for relative
purposes on the same system only. The iterative multi-point methods give
good agreement with experimental data, LLSMq and POLCURR being the best
especially when the fourth corrosion parameter Ecor is included.

Summary: A quantitative comparison of some well known methods for
estimating corrosion parameters icorr,Ecorr,Tafel coefficients and
polarization resistance, is presented. Methods of Barnartt,
Jankowski-Juchnievicz, LeRoy, Chu-nan, Bandy, Green and Gandhi
(BETACRUNCH), Mansfeld (CORFIT i POLCURR) Jensen and Britz, Štern and Aurer
(WT-SA) have been considered. The comparison is based on experimental data
obtained with a system ARMCO-Fe - 0,5 mol/L H2SO4. Potentiostatic technique
was used. The iterative multi-point methods give good agreement with
experimental data, LLSMq, POLCURR and WT-SA being the best, especially when
the fourth corrosion parameter Ecorr is included. In calculations by means
of the WT-SA method direct use of Wagner-Traud model was included. By the
Marquardt iterativ procedure convergence from any resonable initial
estimation is ensured.
