Embodiment 1

[0062] Mold cavity 4 is 101×101mm in size and 8.3mm in depth. Prepare a piece of Q235 steel plate with a specification of 100×100×8mm as the base material 9, a piece of copper foil (copper material 8) with a specification of 100×100×0.3mm, a piece of For a TiAlNb titanium plate (titanium material 7) with a specification of 110×110×1.0mm, place the steel plate in the inner cavity 4 of the mold, cover it with copper foil, and drill a threaded hole matching the threaded hole 3 of the mold around the titanium plate , cover the mold 2, cover the upper strip 5 and align the threaded hole 6 of the upper strip with the threaded hole 3 of the mold, and fix the upper strip 5 and the mold 2 with bolts, that is, compress the steel plate, copper foil and titanium plate into a thick The billet is placed on the laser cladding workbench, and a layer of SiO with a thickness of 0.3mm is coated on the surface of the titanium plate. 2 , to prevent oxidation of the titanium plate; through the mold...

Embodiment 2

[0067] Specifically the same as embodiment 1, the difference is:

[0068] The thickness of the copper foil is 0.2mm, the titanium plate is a Ti3-Al titanium plate with a thickness of 0.6mm, and the anti-oxidation isolating agent is Al 2 o 3 ;

[0069] The process parameters of a laser cladding are: laser power 1000W, flat-top laser, scanning speed 0.8m / min, protective gas (Ar): 0.3m 3 / h;

[0070] The process parameters of secondary laser cladding are: laser power 2000W, flat-top laser, scanning speed 0.15m / min, protective gas (Ar): 1m 3 / h.

Embodiment 3

[0072] Specifically the same as embodiment 1, the difference is:

[0073] The thickness of the copper foil is 0.1mm, and the titanium plate is a Ti-47Al-2Cr-2Nb titanium plate with a thickness of 0.2mm;

[0074] Only one laser cladding is performed, and no secondary laser cladding is performed.

Abstract

The invention relates to the technical field of composite board preparation, in particular to a method for vacuum laser composite preparation of a titanium steel composite board. The method comprisesthe steps that a copper material and a titanium material are placed on the surface of a base material in sequence, a rough blank is formed after a mold is used for edge pressing, laser cladding is carried out after the rough blank in the mold is vacuumized, then cooling is carried out, and the method is completed. Through the laser processing technology, the difficulty of titanium and iron connection is overcome, materials are saved, and meanwhile application of a titanium alloy coating is widened; and a proper transition layer is designed between titanium and iron, the defects of air pores, cracks and the like are reduced, the bonding force between a matrix and a covering layer is enhanced, the titanium steel composite board excellent in performance is obtained, the application cost of titanium is obviously reduced, and the advantages of titanium and iron are successfully combined.

Description

technical field [0001] The invention relates to the technical field of composite plate preparation, in particular to a vacuum laser composite preparation method for a titanium steel composite plate. Background technique [0002] Titanium steel composite plate is a new type of plate material, which not only has the excellent corrosion resistance of titanium metal, but also has the strength and plasticity of the substrate structural steel. Compared with titanium plate, its economic cost is greatly reduced, which can effectively reduce the cost And reduce the consumption of scarce metal resources, it is an ideal material for corrosion-resistant environment equipment. Therefore, it is currently widely used in various chemical reaction vessels, heat exchangers and other anti-corrosion product fields. [0003] The existing production methods of titanium-steel clad plates can be divided into the following four types: explosive clad method, diffusion clad method, explosion-rolling ...
