Description
Technical Field
The invention relates to the technical field of brazing, in particular to a titanium-nickel brazing filler metal for brazing a TiB + TiC hybrid reinforced titanium-based composite material and a nickel-based alloy, and a preparation method and a brazing method thereof.
Background
The ceramic reinforced titanium-based composite material has the dual characteristics of ceramic and metal, has high specific strength and specific stiffness and good high-temperature resistance and corrosion resistance, and has wide application prospects in the fields of aerospace and the like. At present, a great deal of research is carried out on the forming and preparation process, the mechanical property and the like of the ceramic reinforced titanium-based composite material, and a relatively remarkable scientific research result is obtained. Wherein for the reinforcing phase, TiB and TiC have excellent thermodynamic stability and thermal expansion coefficient very close to that of titanium matrix (such as TC4 (Ti 6-Al 4-V) = 8.6 x 10)-6/℃，αTiB= 8.6×10-6/° c and α TiC = 7.2 × 10-6/° c) and chemical compatibilityThereby attracting attention of people. And it is inevitably necessary to bond the ceramic-reinforced titanium-based composite material to itself or other alloys during practical use thereof. For a single titanium alloy, the welding process is mature, and conventional welding methods such as fusion welding and diffusion welding are widely used. However, the ceramic reinforced titanium-based composite material is formed by compounding metal and non-metal materials with greatly different components, structures and properties, and the physical and chemical compatibility between the materials is poor, so if the ceramic reinforced titanium-based composite material is welded with an alloy, the metal-metal and metal-non-metal combined interfaces need to be considered, therefore, compared with a Ti metal matrix, the welding performance of the ceramic reinforced titanium-based composite material is greatly different, and the problem of difficult welding exists.
At present, scientific researchers at home and abroad explore a plurality of connection processes of the ceramic reinforced titanium-based composite material, such as diffusion welding, fusion welding, brazing and the like. The diffusion welding process has high requirements on processing of the surface of a connection sample and connection equipment, needs large connection pressure, has limitations on the size and the shape of a welding piece, and cannot be used for continuous batch production. In the case of fusion welding, the reinforcing phase is more disorderly distributed at the weld due to the higher fusion welding temperature, and once the reinforcing phase is gathered at the weld, a large amount of stress is generated, resulting in a reduction in the strength of the joint.
For brazing solder alloy of the ceramic reinforced titanium-based composite material, scientific researchers explore the alloy components. For example, Chinese patent CN201310137981.X "method for brazing TiBw/TC4 titanium-based composite material by Ti-Zr-Ni-Cu brazing filler metal" is to design Ti-Zr-Ni-Cu amorphous foils so as to realize effective connection of TiBw/TC4 titanium-based composite material; the literature reports that TiBw/TC4 titanium alloy and C/C composite material are brazed and connected by TiZrNiCu active brazing filler metal (Huangchao, Lintiesong, He Peng. interface tissue structure of a brazed joint of TiBw/TC4 titanium alloy and C/C composite material [ J ]. welding science, 2011,32 (7): 39-42.). Chinese patent CN201310150024.0 'A composite solder and a preparation method thereof and a method for brazing TiBw/TC4 titanium-based composite material by using the composite solder' is to uniformly coat TiB2 particles on a TiZrCuNi amorphous foil by using a binder to prepare the composite solder and then braze the TiBw/TC4 titanium-based composite material; chinese patent CN201610092721.9 "a method for connecting Ti60 and TiBw/TC4 by TiZrNiCu + B composite solder" is to braze Ti alloy Ti60 and TiBw/TC4 composite material by TiZrNiCu + B powdered solder; compared with the present application, the brazing filler metal used in the patent or the literature is mainly amorphous TiZrNiCu brazing filler metal, and the preparation process is complex and the cost is high. Furthermore, the document "Lin T.S., Yang M.X., He P., et al.Effect of synthesized TiB whisker on micro structure and mechanical properties of carbon-carbon composite and TiBw/Ti-6Al-4V composite joint. Mater. Des.,2011,32: 4553" the composite solder using Cu-50Ni (wt.%) + TiB2 ceramic successfully obtained a TiBw/Ti-6Al-4V composite/C-C composite solder joint at 918 ℃. 978 ℃, and compared with the present application, the Cu-Ni based superalloy solder has a relatively low melting point.
In summary, the amorphous tizrncu alloy solder or Cu-based alloy solder and the ti-ni alloy solder of the present application have great differences in both the composition of the metal elements and the mass percentage of each element.
In addition, for the welding process, the chinese patent CN201210013046.8 "argon arc welding method for non-continuous reinforced titanium-based composite material" uses argon arc welding to realize the connection between the non-continuous reinforced titanium-based composite material, such as (TiB + TiC)/Ti1100 titanium-based composite material, (TiB + Y2O3)/Ti-6Al-4V titanium-based composite material, etc. The document "Fukumoto S., Kasahara A., Hirose A., et Al, transformed phase dispersion bonding of connecting SiC fiber reinforced Ti-6Al-4V composite to Ti-6Al-4V alloy. Mater. Sci. Technol, 1994, 10: 807" successfully realizes SiC fiber reinforced Ti-6Al-4V composite and Ti-6Al-4V alloy by Transient liquid phase diffusion welding. The documents "silver A.A.M.D., Meyer A., Santos J.F.D., et Al, Mechanical and metallic properties of free-wet TiC particulate repaired Ti-6Al-4V. composite. Sci. technol., 2004, 64(10-11): 1495" welding of TiC reinforced Ti-6Al-4V composite using friction stir welding and studying the law of the effect of the welding process on the performance of the welded joint. However, the friction welding process is complex, the welding pressure is high, and the requirement on equipment is high.
In a word, the welding process can successfully weld the ceramic reinforced titanium-based composite material, but due to the characteristics of the welding processes such as fusion welding, diffusion welding, friction welding and the like, for example, the fusion welding easily causes the ceramic reinforced phase in the composite material to be gathered at the interface, so that the stress of the joint interface is concentrated, and the welding pressure required by the diffusion welding is large, which all become main factors limiting the application of the method. Therefore, how to develop a proper solder alloy and optimize the brazing process becomes a technical bottleneck for the wide application of the ceramic reinforced titanium-based composite material.
