The invention provides a spraying method after textures the surface of an aluminum alloy are etched with laser light. In the spraying method, the aluminum alloy, on the surface of which the textures are etched with the laser light, is sprayed with a mixed and aged coating, wherein the thickness of a coating layer is 40-50 microns, and the textures on the surface of the aluminum alloy is square orrhombus. By using the method to spray the surface of the aluminum alloy, the coating penetrates into a groove etched with the laser light, so that adhesive force of the coating layer is increased. 本发明提供了一种激光刻蚀铝合金表面纹理后的喷涂方法，将混合熟化的涂料喷涂到采用激光刻蚀表面纹理的铝合金上，涂层厚度为40-50μm，所述铝合金表面纹理为正方形或菱形。通过使用本发明的方法对铝合金表面进行喷涂，涂料渗透到激光刻蚀的凹槽内，增加了涂层的附着力。
