The invention discloses a preparation method and application of an oxidized ceramic layer on the surface of zirconium and zirconium alloy. The method comprises the following steps: reducing the roughness of a target area to 0.01 μm or less, performing oxidation treatment in an oxidizing gas atmosphere, and replacing the oxidizing gas with inactive gas. According to the technical solution provided in the present application, the surface roughness is controlled before oxidation treatment, so that the surface roughness after oxidation treatment can satisfy the use requirements; and the inert gas replacement after surface oxidation treatment avoids the removal of a film layer with poor performance formed during the cooling process, thereby completely avoiding the need for later polishing treatment, maintaining the integrity and uniformity of the oxidized ceramic layer, and guaranteeing the protective performance.
