The invention relates to the field of spraying, and particularly relates to a preparation method of a thermal spraying coating on adjacent surfaces. The method comprises the following steps of: preparing a coating A on a surface a according to a preset process specification a; machining the coating A to a preset thickness, wherein the preset thickness is the sum of the final required thickness ofthe coating A and a preset allowance; performing coating chamfering treatment on a lap joint part, which needs to be in lap joint with a coating B, of the coating A; preparing the coating B on a surface B adjacent to the surface a according to a preset process specification B, wherein the coating B covers a coating chamfer of the coating A; and machining the coating A and the coating B to respective final required thicknesses. The preparation method realizes machining of different types of coatings on the adjacent surfaces by thermal spraying. 本发明涉及喷涂领域，尤其是一种相邻表面热喷涂涂层制备方法。方法，其包括：在a表面按照预设a工艺规范制备A涂层；对A涂层进行机械加工，将A涂层加工至预设
