Zirconium hydride composite hydrogen-resistant coating structure and preparation method thereof
The invention discloses a zirconium hydride composite hydrogen-resistant coating structure, and belongs to the technical field of material surface protection. The zirconium hydride composite hydrogen-resistant coating structure comprises a zirconium hydride matrix, and the outer layer of the zirconium hydride matrix is coated with a micro-arc oxidation coating. The outer layer of the micro-arc oxidation coating is also coated with a layer of graphene.
