Abstract

The invention provides a supersonic laser deposition spray gun, a laser deposition device and a laser deposition method. A laser beam channel and a powder and gas mixed beam channel are formed in thesupersonic laser deposition spray gun, a laser beam stretches along the central axis of the supersonic laser deposition spray gun, the powder and gas mixed beam channel is distributed along the periphery of the laser beam channel, and the powder and gas mixed beam channel is provided with a laval spray pipe structure; the laser deposition device comprises the laser deposition spray gun. The laserdeposition method is implemented based on the laser deposition device. The supersonic laser deposition spray gun achieves tight and deep combination between the laser beam and the supersonic powder beam, so that a material is deposited and prepared quickly and efficiently with high quality and low cost. The supersonic laser deposition spray gun has wide popularization and application prospects.

Description

technical field [0001] The invention belongs to the field of advanced manufacturing technology, relates to a surface treatment technology based on material deposition, in particular to a supersonic laser deposition technology, in particular to a supersonic laser deposition spray gun, a laser deposition device and a laser deposition method. Background technique [0002] At present, the deposition technologies in the field of material preparation mainly include the following: PVD, CVD, thermal spraying and laser cladding, etc. These technologies have the following characteristics: [0003] Physical vapor deposition (PVD) is a physical method used under vacuum conditions to vaporize the surface of solid or liquid materials into gaseous atoms, molecules or partial ionization into ions, and through a low-pressure gas (or plasma) process, deposit on the surface of the substrate with Some kind of special functional film technology. PVD can not only deposit metal films, alloy films...
