Technical Field

The invention belongs to the technical field of laser cladding, and particularly relates to a uniform feeding device for 3D printing laser cladding.

Background

Laser cladding, also known as laser cladding or laser cladding, is a new surface modification technique. The method is characterized in that a cladding material is added on the surface of a base material, and is fused with a thin layer on the surface of the base material by using a high-energy-density laser beam, so that a metallurgically bonded cladding layer is formed on the surface of a base layer, and the cladding material is as follows: the laser cladding materials with wide application mainly comprise: nickel base, cobalt base, iron base, titanium alloy, copper alloy, particle type metal base composite material, ceramic material, and the like.

The laser cladding characteristic is as follows: the cladding layer has low dilution degree but strong binding force, is metallurgically bonded with the substrate, and can obviously improve the wear-resisting, corrosion-resisting, heat-resisting, oxidation-resisting or electrical characteristics of the surface of the substrate material, thereby achieving the purpose of surface modification or repair, meeting the specific performance requirements of the surface of the material and saving a large amount of material cost. Compared with surfacing, spraying, electroplating and vapor deposition, laser cladding has the characteristics of small dilution, compact structure, good combination of a coating and a matrix, more suitable cladding materials, large particle size and content change and the like, so the application prospect of the laser cladding technology is very wide.

When laser cladding is carried out, the cladding material and the surface of a base material are directly fused in a traditional mode, so that the time is saved, the feeding is not uniform when the cladding material is fed, and the situations of nonuniform heating and incomplete melting of the cladding material are likely to occur, so that the laser cladding effect is influenced.
