  ABSTRACT: Air Plasma spray process was used to deposit a conventional and nanostructured Al2O3-13 wt% TiO2 coatings on a stainless steel substrates. Morphology of the powder particles, microstructure and phase composition of the coatings were characterized by XRD and SEM. Potentiodynamic polarization tests and Electrochemical Impedance Spectro- scopy (EIS) were used to analyze the corrosion of the coated substrate in 3.5% NaCl solutions to determine the opti-mum conditions for corrosion protection. The fatigue strength and hardness of the coatings were investigated. The experimental data indicated that the nanostructured coated samples exhibited higher hardness and fatigue strength compared to the conventional coated samples. On the other hand, the conventional coatings showed a better localized corrosion resistance than the nanostructured coatings.
