Embodiment 1
[0043] Embodiment 1 A method of supersonic laser deposition micro-peening, specifically comprising the following steps:
[0044] Take the part to be repaired as the base material, firstly polish the base material, and then use 24# white corundum to perform sandblasting treatment under the air pressure of 1.0MPa to improve the surface roughness and remove surface oxides, and then put it into an ultrasonic cleaning machine Wash to remove surface impurities, then wash with absolute ethanol, then wipe dry and put it in a vacuum drying oven to preheat (temperature 120°C, time 0.5h), and fix the treated substrate on the workbench. Spherical particles of large particle size alumina (particle size is 120 ~ 150μm, such as figure 1 As shown, the alumina volume ratio is 30vol.%) and Cu powder are fully mechanically mixed (ball milled at 300rpm for 30min) and then dried (dried at a drying temperature of 120°C for 3 hours), and then poured into a powder feeder. Set the spray carrier gas (...
