Embodiment Construction
[0036] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:
[0037] The thin-wall structure ultrafast pulse laser-cold spraying surface processing method provided by the invention comprises the following steps:
[0038] Construct defect process parameter database;
[0039] Construct the surface three-dimensional model of thin-walled structural defects;
[0040] Identify defect features and calculate defect repair parameters;
[0041] Calculate the trajectory of each moving part;
[0042] Provide a laser-cold spraying system, including a cold spraying system, a control module, a laser system, a motion system and a powder charging device, the laser system is used to emit ultrashort pulse laser, so that the matrix material and powder particles can quickly reach a thermoplastic state; The nozzles of the above-mentioned cold spray system and ultrashort pulse laser system are loaded on the motion system...
