Problems solved by technology

However, some products require strong connection strength, and the connection strength of these products cannot be satisfied by adhesive connection.
In addition, because it is difficult to realize the tapping process on amorphous alloy materials, it is difficult to realize the structure of bolts and nuts on amorphous alloy products. Moreover, if adhesives are used to bond bolts and nuts to amorphous alloy products, Its connection strength cannot meet the needs of production

Abstract

The invention relates to the technical field of amorphous alloys, in particular to an amorphous alloy and nut welding method. According to the method, an amorphous alloy base material and a nut are involved, protected by an inert atmosphere, a rotating device is adopted for driving the nut at a certain rotating speed and feeding speed to rotate and press the amorphous alloy base material, and the nut rubs with the amorphous alloy base material to generate heat, so that the temperature of the amorphous alloy base material reaches in a supercooling liquid phase range above the temperature Tg and below the temperature Tx or reaches above the temperature Tm, and the amorphous alloy base material is in a viscous supercooling liquid phase range or a molten (over the melting point) state and then is connected with the nut; the amorphous alloy base material is provided with a groove used for being welded to the nut, and the rotating device is provided with a protective gas nozzle for blowing the inert atmosphere to the amorphous alloy base material. The amorphous alloy base material and the nut are connected, the problem that an amorphous alloy is difficult to tap is solved, and the application range of the amorphous alloy is enlarged substantially. The connection force between the amorphous alloy and the nut is large, and the quality of the surface of the welding area is high.

Description

technical field [0001] The invention relates to the technical field of amorphous alloys, in particular to a welding method for amorphous alloys and nuts. Background technique [0002] Amorphous alloys have been applied in the fields of electronics, machinery, and chemical industry because of their excellent properties in terms of strength, hardness, toughness, wear resistance, corrosion resistance, soft magnetism, and superconductivity. [0003] However, although the amorphous alloy has the above-mentioned excellent characteristics, it has the disadvantages of being difficult to process and weld, which greatly limits its application range. Therefore, the welding of amorphous alloys has become a technical difficulty in expanding the application of amorphous alloys. [0004] In practical applications, the connection between amorphous alloy and crystalline metal is mainly connected by adhesive. However, some products require strong connection strength, and the connection stre...
