Description

technical field [0001] The invention relates to the field of surface modification and remanufacturing, in particular to a supersonic laser composite deposition device for inner walls. Background technique [0002] Supersonic laser deposition is a new surface modification technology that combines laser irradiation with cold spray technology. This technology uses laser as an auxiliary heat source. During the deposition process, the laser irradiation spot and the spraying powder spot are synchronized to realize synchronous heating of the sprayed particles, the deposition area or the deposited coating. With the help of the rapid heating capability of the high-energy beam laser, it can instantly improve Or adjust the mechanical properties and collision deposition state of the deposition particles and materials in the deposition area, improve the thickness, deposition efficiency, density and bonding strength of the low-pressure cold spray coating, and then improve the performance ...

AI Technical Summary

Problems solved by technology

However, the existing supersonic laser deposition spray gun cannot be used for coating preparation on the surface of the inner hole due to the limitation of the spraying space and the fact that the nozzle extending into the hole cannot be perpendicular to the inner wall.
