Laser cladding preparation device for ceramic reinforced metal matrix composite coating

Abstract

The invention discloses a laser cladding preparation device for a ceramic reinforced metal matrix composite coating, and belongs to the field of laser welding, the laser cladding preparation device comprises a base, a first supporting plate, a second supporting plate, a top plate and a connecting arm, the bottom of the top plate is provided with an XYZ displacement platform through bolts, and the displacement end of the XYZ displacement platform is provided with a displacement plate; mounting frames are welded to the two ends of the bottom of the displacement plate, servo electric cylinders are mounted at the bottoms of the mounting frames through screws, vertical plates are connected to the power output ends of the servo electric cylinders, extension plates are welded to one sides of the vertical plates, and second servo motors are mounted at the bottoms of the extension plates through screws; and the power output end of the second servo motor penetrates through the vertical plate and is connected with a rotating arm. Mixed powder can be conveniently preset, the preset powder can be rapidly melted, the solid solubility of a base body at the welding position can be increased, accordingly, a metastable phase is formed, the strength of the welding position is greatly improved, and the device is suitable for being widely used and popularized.

Description

technical field [0001] The invention belongs to the technical field of laser welding, and in particular relates to a laser cladding preparation device for a ceramic-reinforced metal-based composite coating. Background technique [0002] Laser cladding began in 1974 and emerged in the 1980s. It is a new type of material processing and surface modification technology, which can make a high-performance surface layer on a low-cost material substrate, replace a large number of precious alloys, and optimize resource allocation. , in order to save precious and rare metal materials and reduce energy consumption, it is suitable for parts that are easily worn, impacted, oxidized and corroded, and require special performance locally, and have received widespread attention at home and abroad. As a new metal surface strengthening technology, it is also a very active research direction in the field of material surface laser treatment. It can form a few microns to several millimeters thic...

AI Technical Summary

Problems solved by technology

However, the research and application of cladding technology and laser materials are still in their infancy.

[0004] In the past, in the cladding process, it was not convenient to preset the mixed powder, and the preset powder could not be melted quickly, and the solid solubility of the matrix could not be increased at the weld, thus forming a metastable phase, and the strength of the weld was low
