Embodiment 1

[0022] according to Figure 1~2 The composite slab structure and production method of the present invention are described in detail. The production method of titanium-steel-titanium composite plate diffusion welding includes the following steps: material selection - surface treatment - blank assembly (peripheral spot welding - making sheath - welding conduit - air tightness inspection - vacuuming) - slab pressurization - Diffusion welding - clear jacket - clear spot welding meat.

[0023] It mainly involves the following equipment: shearing machine, grinding machine, argon arc welding machine, air pump, hydraulic press, vacuum pump, diffusion pump, etc.

[0024] Specifically, it includes the following steps:

[0025] 1) Select cladding plate 1 (titanium plate), substrate 2 (steel plate), transition layer 4 (pure iron sheet or pure copper sheet). Cut the steel plate, titanium plate, pure iron sheet or pure copper sheet on the shearing machine according to the process size, a...

Embodiment 2

[0032] The thickness ratio of the titanium plate to the steel plate is 1.5:10; the release agent is a mixture of magnesium oxide powder and talcum powder with a weight ratio of 1.0:0.6. Other steps are with embodiment 1.

Embodiment 3

[0034] The thickness ratio of the titanium plate to the steel plate is 1.2:10; the release agent is a mixture of magnesium oxide powder and talcum powder with a weight ratio of 1.0:1.6. Other steps are with embodiment 1.

Abstract

The invention discloses a production method for titanium steel titanium composite board diffusion welding. The technical key point is that the method comprises the following steps that 1, a steel plate, a titanium plat and a pure iron thin plate or a pure copper thin plate are cut, the combination surfaces are polished for standby use; 2, the above materials form two groups of composite board blanks, a parting compound is smeared between the two groups of composite board blanks, the composite board blanks are placed in a cover made of low-carbon steel, the contact surfaces between the upper and lower titanium plates and the cover are smeared with the parting compound, a degassing hole is formed in the side face of the cover, a guide pipe is welded in the degassing hole, and the gas tightness is detected; 3, the cover is vacuumized to the vacuum degree less than 0.001 Pa; 4, an oil press is used for pressing the composite board blank and the cover, the vacuum is kept during pressing, the composite board blank is heated to 880-950 DEG C for the diffusion welding of the composite board blank, and the composite board blank is cooled in the air to room temperature; 5, the cover is removed, the spot welding beads at the periphery are removed, and two titanium steel titanium composite boards are obtained. The method is free of the influence of seasons and environmental pollution, the production scale and the product specification are controllable, and the boundedness that only a thin plate can be manufactured by a continuous hot rolling manufacturing method is avoided.

Description

technical field [0001] The invention relates to the technical field of metal composite materials, in particular to a production method of diffusion welding of titanium-steel-titanium composite plates. Background technique [0002] Titanium is a silver-white transition metal characterized by light weight, high strength, metallic luster, and good corrosion resistance (including seawater, aqua regia, and chlorine gas). Because of its stable chemical properties, good high temperature resistance, low temperature resistance, strong acid resistance, strong alkali resistance, high strength and low density, it is known as "space metal". However, its use cost is relatively high, especially when it is used as a structural component. In order to reduce the cost of use, it is usually made of titanium-steel-titanium composite plate. Not only has the corrosion resistance of titanium, but also has the strength of ordinary steel plates, which greatly reduces the cost of use. [0003] The ...
