Abstracts
The corrosion damages significantly reduce the use-value and shorten the life time of various constructions. As a result of corrosion damages occur enormous costs, and sometimes major disasters which can lead to the material costs and also dangerous consequences for human life. With proper selection of structural material and its corrosion protection these unpleasant consequences can be avoided or significantly reduced. Every material has a different corrosion behavior depending on the physical conditions and medium in which it is located.
In this work the influence of medium and microstructure on corrosion rate of dual phase high-strength structural steels was studied. The electrochemical measurements revealed that both examined dual phase steels showed lower corrosion rate in the medium of 5 % NaOH, than in the medium of 5 % H2SO4. The metallographic analysis of investigated materials indicated the fact that the amount of martensite phase and morphology of microstructural constituents have a significant effect on the corrosion behavior of dual phase steels. Namely, with decreasing the amount of martensite in dual phase steels corrosion rate increases in both examined media.
