Amorphous welding is a very complex skill in the welding industry, and about amorphous welding materials, it is a new type of material, so what are the applications and production methods of amorphous welding materials? let's see it together!
First, the application of amorphous welding materials
1. Application of copper-based amorphous soldering materials
The copper-based amorphous welding material can be made into the required shape according to the needs, has high fluidity, and can replace the traditional alloy material. Now it is most used in the field of low-voltage electrical contact materials. Copper-based non-static welding materials can also be used in the commutator, which can be used satisfactorily. In the copper-based amorphous welding material, many elements such as Ni, Sn, and P are added, which further improves the strength and fluidity of the product material.
2. Application of nickel-based amorphous welding materials
Nickel-based amorphous welding materials mainly exist in the form of sticky tape and powder, and the production cost is relatively high. It has a good development prospect and can be used in the fields of machinery, atomic energy, and aerospace. At present, nickel-based amorphous welding materials have been It has been used in the production of oil coolers, precision instruments and other equipment.
3. Application of low temperature amorphous welding materials
Low-temperature amorphous soldering materials are mainly used in printed circuits and electronics industries. Commonly used are tin-lead low-temperature amorphous soldering materials and aluminum-based amorphous soldering materials. This kind of material mostly exists in the form of powder or rolled products, which can suppress the occurrence of cracks and improve the heat-resistant fatigue ability of the material.
4. Application of aluminum-based amorphous welding materials
Aluminum-based amorphous soldering materials are the most widely used materials at this stage and are suitable for use in the production of electronic devices. However, the melting point of aluminum-based amorphous soldering materials is high. In order to reduce the melting point of the material, it is possible to add Elements such as chromium and copper. In addition, the rapid setting method can also be used to improve the strength of the material.
5. Application of other amorphous welding materials
In addition to the above-mentioned common materials, there are also ceramic, graphite and titanium alloy amorphous welding materials. These materials also have very good properties, especially heat resistance and oxidation resistance, which are more excellent, but the cost is high. This also makes the application of such materials more obvious.
Second, the production method of amorphous welding materials
At present, the most common method for producing amorphous welding materials is the high-pressure compaction method. The high-pressure compaction method can effectively suppress the crystallization of the alloy, so that the material exhibits a uniform viscous flow, thereby filling the voids and voids of the strip and powder, and completing the material full fine fit. With the development of skill level, a new welding method such as conflict welding was born. Practice shows that in the supercooled liquid phase, some metallic glasses will exhibit strain rate superplasticity, and in the process of amorphous material conflict, the heat will increase significantly , After the welding area reaches the supercooled liquid phase area, the superplasticity of the opposite sex is shown. If there is a problem of superplastic change, the supercooled liquid will flow out and destroy the oxide film on the surface of the material. At this moment, the welding is completed. function.
Amorphous welding materials have an outstanding application trend in the industry. At present, the research on such materials has deepened the aging mechanism, welding dispersion behavior, amorphous composition ability, and the influence of crystallization on the welding process. With the development of the industrial level, the demand for non-static welding materials is also increasing. Amorphous welding materials will become a very promising material in the next stage. Strengthening the research and implementation of this material will further promote With the progress of welding foundation, in the new historical stage, amorphous welding materials will also usher in new development opportunities.
