Abstract

The invention relates to a composite soldering material, a preparation method thereof and a method of using the composite soldering material to solder a TiBw / TC4 titanium-based composite material, and aims at solving the problem that joints with high high-temperature strength are difficult to obtain by using a single soldering material to solder the titanium-based composite material. The composite soldering material is prepared by uniformly coating TiB2 particles on the surface of TiZrCuNi amorphous foil by binder. The soldering method includes: 1, grinding a base material; 2, cleaning the base material; and 3, soldering. By adopting the composite soldering material prepared by the method, effective connection of the TiBw / TC4 titanium-based composite material can be realized, and a connecting joint has high high-temperature strength. The composite soldering material prepared by the method is used for soldering the TiBw / TC4 titanium-based composite material.

Description

technical field [0001] The invention relates to a composite solder, a preparation method and a method for brazing composite materials with the composite solder. Background technique [0002] As an important class of engineering materials, titanium alloy has the advantages of low density and high room temperature strength, and is widely used in aerospace, chemical industry, biomedicine and marine engineering and other fields. However, the disadvantages of titanium alloys such as poor wear resistance and low high-temperature strength limit the application of titanium alloys to a large extent. Adding high-strength, high-hardness ceramic reinforcements to ferroalloys to prepare titanium-based composites can significantly improve their room-temperature mechanical properties and high-temperature creep strength, allowing them to be further used in commercial vehicles, aerospace and advanced military applications. [0003] Titanium matrix composite reinforcements can be divided int...
