Method for preparing anti-uranium-tantalum-oxide film on metal uranium surface

The invention provides a method for preparing an anti-uranium-tantalum-oxide film on the metal uranium surface, belongs to the technical field of material surface treatment, and particularly relates to a method for preparing an anti-uranium-tantalum-oxide film for protecting a metal uranium material surface, aiming at solving the problem that a metal uranium material has active chemical property,and is extremely easily oxidized, etched and failed in application. The method comprises the step of preparing an anti-uranium-tantalum-oxide film on the surface of a metal uranium film or metal uranium block from a uranium-tantalum alloy target which serves as a target by adopting direct-current magnetron sputtering; or preparing the anti-uranium-tantalum-oxide film on the surface of a metal uranium film or metal uranium block from a metal uranium target or metal tantalum target which serves as a target by adopting dual magnetron sputtering co-deposition method.
