Abstract
The electrochemical corrosion behaviours of the steel substrates coated with three different plasma sprayed Al2O3–13%TiO2 coatings were studied in this paper. The three kinds of Al2O3–13%TiO2 coatings were conventional ME coating, nanostructured NP coating and NS coating. There were micro cracks, laminar splats and straight columnar grains in ME coating. For the two nanostructured coatings, the laminar microstructure and columnar grains were not obvious. The NP coating had the highest hardness and spallation resistance. Electrochemical corrosion behaviour of the three coatings was mainly investigated by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) in aqueous Na2SO4 solution.
