Effects of pre-sputtered Al interlayer on the atomic layer deposition of Al2O3 films on Mg-10Li-0.5Zn alloy

► Deposition of a dual-layer Al/Al2O3 films on Mg-10Li-0.5Zn substrate using both techniques of magnetron sputtering and atomic layer deposition (ALD). ► Identify the crystal structure, chemical composition, surface morphology of the dual-layer Al/Al2O3 films. ► Clarify the effects of dual-layer Al/Al2O3 films on the corrosion resistance of Mg-Li alloys.
