The invention discloses a preparation method of a plasma assisted laser textured PVD coating layer on the surface of a basal body. A microtexture is machined on the surface of the basal body by adopting femtosecond laser; then, the surface of the basal body is etched by using a plasma; and finally, a PVD coating layer is deposited on the textured surface of the basal body to obtain the basal bodywith the PVD coating layer. The method can increase the specific surface area of the surface of the basal body to improve the mechanical embedding effect between the coating layer and the basal body,uses a plasma assisted laser processing method for high-quality controllable preparation of the regular microtexture on the surface of the basal body with the coating layer, and can improve the physical bonding and chemical bonding interfaces between coating layer film bases to further improve the bonding strength of the coating layer film bases and to improve the bonding force between the coatinglayer and the basal body in a stated shape area. The method is particularly suitable for preparation of PVD coating cutters of high-speed steel or hard alloy steel basal bodies, and can effectively improve comprehensive performances of the cutters.
