Investigated Microstructure of Al₂O₃/13wt%MgO Nanocomposite Coating Prepared by Plasma-Sprayed Technique

Abstract:

The MgO nanowire growth on Al₂O₃ lamellae has been placed on plasma-sprayed process. The chemical compositions of nanocomposite powders were appeared α-Al₂O₃ and cubic-MgO phases. After deposited by plasma sprayed coating, the chemical composition has presented major of γ-Al₂O₃, minor of α-Al₂O₃ and cubic-MgO phases. The microstructure of Al₂O₃/13wt%MgO coating was exhibited high density and good distribution of MgO lamellae with thickness in range 241 μm. The MgO nanowire had dispersion that width diameter in range of ~96.5 nm and average of length 884.9 nm, on the Al₂O₃ lamellae. The result of nanostructure MgO nanowire generation could be explained that the MgO clusters have been depressed on the Al₂O₃ lamella at the low temperature zone, then deposited and nucleated in during plasma-sprayed. It was found that the new phase of spinel Al₂MgO₄ form interaction between Al₂O₃ and MgO. The average porosity of ∼14% was observed in Al₂O₃/13wt%MgO nanocomposite coating.
