The invention provides an anti-oxidation structure and a method for forming the anti-oxidation structure. The anti-oxidation structure comprises a base body and a closed microstructure, the closed microstructure is a cavity with two open ends in the vertical direction, the lower end of the closed microstructure is arranged on the surface of the base body, and when oxidation films are formed inside and outside the closed microstructure on the surface of the base body, the thickness of the closed microstructure is smaller than that of the closed microstructure. And the oxide film formed in the closed microstructure is subjected to pressure stress, so that the thickness growth rate of the oxide film is reduced. By the adoption of the technical scheme, the growth rate of an oxidation film formed in the closed microstructure on the surface of the base body of the anti-oxidation structure can be reduced, the oxidation process of the base body of the anti-oxidation structure in the closed microstructure is slowed down, selective improvement of the surface oxidation resistance of the base body is achieved, and the service life of the anti-oxidation structure is prolonged. Therefore, guidance is provided for design of a thermal protection material, and a powerful means is provided for property regulation and control of the material.
