The invention provides a superhydrophobic ceramic coating and a preparation method thereof. The superhydrophobic ceramic coating is prepared through the steps that a substrate is pretreated, and the substrate is coated or sprayed with a mixture of a polysilazane organic polymer ceramic precursor and filler, wherein the filler is ferrocene or tetrabutyl titanate; under the protection of inert gas,a coating layer is subjected to laser scanning, ceramic conversion is achieved, and the ceramic coating is obtained. According to the method, compared with a traditional high temperature sintering method, sintering is not needed, and energy consumption is reduced; laser energy is concentrated, the heat affected zone is small, the substrate phase composition is not affected, the problem that when the ceramic coating is prepared through the single polysilazane organic polymer ceramic precursor, due to the fact that laser pyrolysis micromolecules overflow, the coating surface has cracks and air holes can be effectively solved, and the obtained ceramic coating has the high hardness and corrosion resistance and the excellent super-hydrophobicity.
