Preparation of zirconia-magnesia nanocomposite powders and coating by a sucrose mediated sol-gel method and investigation of its corrosion behavior

The zirconia-magnesia nanocomposite powders and coating were prepared using a new sucrose- mediated sol-gel method. The effect of sucrose content to metal ions and calcination temperature on the morphologies and phase of the products were investigated. The samples were characterized by XRD, FTIR and FE-SEM analysis. The results showed that the cubic phase of ZrO2-MgO with an average size of 30 nm was formed in the presence of sucrose as a gel agents. Finally, the corrosion behavior of optimized sample has been evaluated.
