A multi-axis linkage spraying device and spraying method for a thermal barrier coating on the surface of a special-shaped structural part. The multi-axis linkage spraying device includes a three-dimensional modeling unit, a multi-axis linkage plasma spraying unit, and a thickness monitoring and feedback unit; the multi-axis linkage automatic spraying method, The method comprises the following steps: 1) three-dimensional modeling; 2) off-line programming of profiling spray trajectory program; 3) multi-axis linkage automatic plasma spraying. The coating prepared by the invention adopts the multi-axis linkage spraying device and the automatic spraying method has high efficiency, good quality, high uniform thickness and consistency, has the characteristics of high precision, high efficiency and low consumption, and reduces the requirements of workers for the operation level. It avoids the huge workload of obtaining the spraying trajectory program by manual teaching, reduces the restriction of the external shape characteristics of the workpiece on thermal spraying, and realizes the real-time monitoring and characterization of the thickness of the thermal barrier coating. Coating preparation provides a convenient way.
Description
technical field [0001] The invention belongs to the technical field of surface engineering, and relates to a spraying device and a spraying method. Background technique [0002] Thermal barrier coatings are widely used in hot-end components working under high-temperature hot air flow conditions to provide high-temperature thermal insulation protection. Its application scope in my country's advanced aero-engines continues to expand, but the shape of engine hot-end components is relatively complex and special-shaped, so The corresponding coating preparation process has low controllability, poor coating quality stability, short coating service life and other problems, which have become the "bottleneck" affecting the application of thermal barrier coatings in aero-engine hot-end components in my country. [0003] At present, domestic thermal barrier coating spraying operations mostly use manual spraying and mechanized spraying. The quality of the coating obtained by manual spray...
