| Abstract: | Electrochemical impedance spectroscopy and linear polarization revealed the superiority of zinc aluminum polyphosphate compared to strontium aluminum polyphosphate. Film formation on the surface of steel samples was confirmed for both pigments through surface analysis. However, scanning electron microscopy and energy dispersive X-ray analysis showed that the composition and morphology of the precipitated layers were different for the two types of pigments. |
