| Opis: | This paper gives an approach to the corrosion resistance analysis and changes in the
chemical composition of anNiTi alloy in the shape of a disc, depending on different real seawater
environments. The NiTi discs were analysed after 6 months of exposure in real seawater environments:
the atmosphere, a tidal zone, and seawater. The corrosion tests showed that the highest corrosion rate
for the discs is in seawater because this had the highest value of current density, and the initial disc
had the most negative potential. Measuring the chemical composition of the discs using inductively
coupled plasma and X-ray fluorescence before the experiment and semiquantitative analysis after
the experiment showed the chemical composition after 6 months of exposure. Furthermore, the
applied principal component analysis and cluster analysis revealed the influence of the different
environments on the changes in the chemical composition of the discs. Cluster analysis detected small
differences between the similar corrosive influences of the analysed types of environments during the
period of exposure. The obtained results confirm that PCA can detect subtle quantitative differences
among the corrosive influences of the types of marine environments, although the examined corrosive
influences are quite similar. The applied chemometric methods (CA and PCA) are, therefore, sensitive
enough to register the existence of slight differences among corrosive environmental influences on
the analysed NiTi SMA. |
