The present application discloses a polyurethane-ceramic composite coating and a spraying method. The coating includes two base materials, namely, a bottom layer and a surface layer. The bottom layer is arranged on a surface of a wind power blade and is a polyurethane base material, and the surface layer is arranged on the bottom layer and is a ceramic base material.
