Study of antioxidation behavior of ultra-thin films for Ce metal surface protection with atomic layer deposition upon air exposure
Year: 2022
Type: article
Abstract: Cerium (Ce) is an easily oxidized metal and the surface oxide layer will break into powders in a few days in air, which is extremely similar to actinide metals like thorium, uranium. To protect the surface of Ce, different ultra-thin films including Al2O3, TiO2, TiN and ZrO2 were deposited on the surface of Ce samples using atomic layer deposition (ALD). All these films decreased the Ce surface oxidation for one month. The Al2O3 film grown by ALD provided best antioxidation effect for 70 days of air exposure. This work shows the potential of ALD in the application of surface antioxidation for actinide metals in the aspect of short time (one month) storage.
