Description
Technical field
The present invention relates to soldering tech fields, and in particular to a kind of soldering TiB+TiC hybrid buildup titanium composite material with
The titanium nickel solder of nickel-base alloy and preparation and method for welding.
Background technique
Ceramics enhancing titanium composite material has both ceramics and the double grading of metal, have high specific strength, specific stiffness and
Good resistant to high temperatures and corrosion resistance has broad application prospects in fields such as aerospaces.Currently, enhancing for ceramics
The molding of titanium composite material and preparation process, mechanical property etc. have carried out a large amount of research, and achieve more significant section
It is ground into fruit.Wherein for reinforced phase, TiB and TiC due to possess excellent thermodynamic stability and with Titanium base very
Similar thermal expansion coefficient (such as TC4(Ti6-Al4-V)=8.6 × 10-6/ DEG C, TiB=8.6 × 10 α-6/ DEG C and TiC=7.2 α
×10-6/ DEG C) and chemical compatibility, so as to cause the concern of people.And in the practical application of ceramics enhancing titanium composite material
It inevitably needs for it to be attached with itself or other alloys in the process.For single titanium alloy, Welder
Skill is more mature, and conventional welding method such as fusion welding, diffusion welding (DW) etc. is widely used.And it is compound for ceramics enhancing titanium-based
Material because its metal for being differed greatly by ingredient, structure and performance and nonmetallic materials are combined, physics between them,
Chemical compatibility is poor, if welding it with alloy, needs to consider metal-metal, the combination interface of metal-non-metal,
Therefore, compared with Ti metallic matrix, the welding performance of ceramics enhancing titanium composite material has very big difference, and it is tired to there is welding
Difficult problem.
Currently, scientific research person has carried out many spies to the Joining Technology of ceramics enhancing titanium composite material both at home and abroad
Rope, such as diffusion welding (DW), fusion welding and soldering.Wherein diffusion technology for welding is to the processing of connection specimen surface and wanting for connection equipment
It asks high, needs big connection pressure, and the size and shape of butt-welding fitting are restricted, the production of continuous batch formula can not be carried out.It is right
For fusion welding, since fusion welding temperature is higher, distribution of the reinforced phase in commissure is more chaotic, once reinforced phase is poly- in weld seam
Collection will have a large amount of stress to generate, and strength of joint is caused to reduce.
For the brazing solder alloy of ceramics enhancing titanium composite material, researcher visits alloying component
Rope.As Chinese patent CN201310137981.X " utilizes the side of Ti-Zr-Ni-Cu solder brazing TiBw/TC4 titanium composite material
Method " is that effective connection of TiBw/TC4 titanium composite material may be implemented by designing Ti-Zr-Ni-Cu amorphous paillon；Document

TiZrNiCu+B powdered filler metal is brazed titanium alloy Ti60 and TiBw/TC4 composite material；Above-mentioned patent or document and the application phase
Than solder used is mainly amorphous TiZrNiCu solder, and preparation process is complicated, higher cost.In addition, document " Lin T.S.,
Yang M.X.,He P.,et al.Effect of in situ synthesized TiB whisker on

The composite soldering of porcelain successfully obtains TiBw/Ti-6Al-4V composite material/C-C composite soldering at 918-978 DEG C and connects
Head, in comparison with the present application, Cu-Ni based ultra-high temperature solder alloy fusing point are relatively low.
In short, above-mentioned amorphous TiZrNiCu solder alloy or Cu based alloy solder and the Ti-Ni alloy solder of the application regardless of
It is to have very big difference on metallic element composition or in the mass percentage content of its each element.
In addition, Chinese patent CN201210013046.8 be " discontinuous reinforcement titanium composite material for welding procedure

Connect the affecting laws of joint performance.But friction welding technological is complicated and welding application pressure is larger, the high requirements on the equipment.
In short, said welding method successfully can enhance titanium composite material by welding ceramics, but due to fusion welding, expansion
The characteristics of dissipating the welding procedures such as weldering and friction welding (FW) is gathered as fusion welding easily causes the ceramic enhancement phase in composite material in interface
Collection causes joint interface stress to be concentrated, and welding pressure needed for diffusion welding (DW) is big, all become limitation such method application it is main because
Element.Therefore how by researching and developing suitable brazing filler metal alloy and optimization soldering processes, it is wide to become ceramics enhancing titanium composite material
The technical bottleneck of general application.
