چکیده مقاله:
Conventional and nanostructured zirconia coatings were deposited on In-738 Ni supper alloy by atmospheric plasma spray technique. The oxidation was measured at 1100°C and hot corrosion resistance of the coatings were measured at 1050°C using an atmospheric electrical furnace and a fused mixture of vanadium pent oxide and sodium sulfate salt respectively. According to the experimental results nanostructured coatings showed a better oxidation and hot corrosion resistance than conventional ones. The improved oxidation resistance could be explained by the change of structure to a dense and more packed structure in the nanocoating. The improvement in hot corrosion resistance was not as good as the oxidation but much better than conventional coating.
