A kind of titanium alloy laser cladding forming method

Abstract

The invention discloses a titanium alloy laser cladding forming method. The laser cladding is formed in a vacuum chamber with a sealed chamber. The sealed chamber of the vacuum chamber is provided with a multi-axis motion platform, and is installed on the A laser head with internal powder feeding on a multi-axis motion platform, the laser cladding forming method includes the following steps: ensuring that the sealed chamber is closed; vacuuming the sealed chamber; introducing protection into the sealed chamber gas, and keep the pressure in the sealed chamber at the set value; start the laser, and the multi-axis motion platform drives the laser head for powder feeding in the light to follow the preset track on the workpiece to be processed in the sealed chamber Focusing the laser beam, the input titanium alloy powder beam moves on the workpiece to be processed with the laser beam to realize the cladding process of the titanium alloy, avoiding the oxidation of the titanium powder during the process, and ensuring the quality of the laser cladding molding.

Description

technical field [0001] The invention relates to a titanium alloy laser cladding forming method. Background technique [0002] Laser cladding is a new surface modification technology. It adds cladding materials on the surface of the substrate and uses a high-energy-density laser beam to fuse it together with the thin layer on the surface of the substrate. Added cladding layer for metallurgical bonding. In order to achieve the purpose of surface modification or repair, it not only meets the requirements for the specific performance of the material surface, but also saves a lot of precious elements. Compared with surfacing, spraying, electroplating and vapor deposition, laser cladding has the characteristics of small dilution, compact structure, good combination of coating and substrate, many materials suitable for cladding, large changes in particle size and content, etc., and has broad application prospects . [0003] At present, in the laser cladding process, the laser he...

Problems solved by technology

[0003] At present, in the laser cladding process, the laser head for powder feeding in the light is usually installed on the mechanical arm, and the cladding process is realized by controlling the movement of the mechanical arm. This laser cladding process is only suitable for cladding of iron powder. processing, which cannot meet the requirements of metal powders with high processing environment requirements, such as laser cladding processing of titanium alloy powders
