Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
Please refer to fig. 1 to 3. It should be understood that the structure, ratio, size and the like shown in the drawings attached to the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any structure modification, ratio relationship change or size adjustment should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the function that the present invention can produce and the purpose that the present invention can achieve. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.
As shown in fig. 1, the present invention provides a thermal barrier coating spraying method, which includes: before spraying, a shielding piece 3 is arranged at a position of a preset distance right ahead of a chamfer required to be formed on a surface to be sprayed, a nozzle of a spray gun 5 is vertically towards the surface to be sprayed, and the spray gun is moved to finish spraying. The utility model adopts a non-contact shielding mode, namely, the shielding piece 3 is arranged in front of the part 4, and the spray gun 5 is vertically sprayed to form the thermal barrier coating 100 with chamfers, thereby accurately controlling the spraying area of the thermal barrier coating and the chamfer spraying of the edge position; additionally, the utility model discloses still can realize the batch operation requirement, only need the position through adjustment shielding piece 3 and then adjust the distance between shielding piece 3 and part 4, realize treating the spraying region of spraying face and the control of coating edge angle, save the time cost and the technology degree of difficulty greatly, improve production efficiency, guarantee thermal barrier coating 100's spraying quality stability.
In this embodiment, the predetermined distance is matched with the size of the chamfer on the surface to be sprayed, as shown in fig. 3, that is, the predetermined distance between the shielding member 3 and the surface to be sprayed is determined according to the size of the chamfer θ to be formed.
When moving, the spray gun 5 performs horizontal or vertical parallel motion in the same plane. Before spraying, the part 4 and the shielding piece 3 are positioned and clamped, and the surface to be sprayed on the part 4 faces the shielding piece 3. In this embodiment, after the part 4 is positioned, the thermal barrier coating 100 may be sprayed, the spray gun 5 is perpendicular to the surface of the part (i.e. the surface to be sprayed) to increase the bonding strength between the thermal barrier coating and the substrate, and during the spraying process, the spray gun 5 may move horizontally or vertically to sweep over the part 4, so that the thermal barrier coating completely covers the surface of the part.
