Abstract
Two TiO2 coatings were plasma sprayed, using an aqueous suspension as a feedstock onto initially prepared alumina substrates. Their thickness was about 7 and 15 μm. The coatings were tested using impedance spectroscopy (IS) in the frequency range from 100 Hz to 2 MHz at temperatures ranging from 320 to 1020 K. The measurements allowed to find the Nyquist plots and equivalent circuits of the tested samples. The IS results were interpreted by the microstructural features of the deposits such as chemical composition, atomic structural and phase analysis. The mechanism of electric current conduction in tested coatings was proposed.
