Influence of deposition conditions on electrical and mechanical properties of Sm2O3-doped CeO2 thin films prepared by EB-PVD (+IBAD) methods. Part 1: Effective relative permittivity

► We have developed a facile method of creating a hydrophobic surface on a magnesium alloy by an immersion process. ► The distribution of micro-structure and roughness of the surface play critical roles from hydrophilic to hydrophobic. ► The hydrophobic coatings possess better corrosion resistance than magnesium alloy matrix.
