High Precision and Difficult Processing Technology Exhibition 2023

Joining precision parts without melting the base material.

This time, I would like to introduce examples of joining using silver solder. There are various methods for joining metals, such as gas welding, arc welding, laser welding, and electron beam welding, all of which involve melting the base material to join them. On the other hand, in the case of brazing, a filler material with a lower melting point than the base material is melted to join the parts, allowing for the joining of complex shapes or precision parts without melting the base material. Additionally, with metallization treatment, it is also possible to join metals and ceramics. The common method for melting the filler material is using a gas burner, but high-frequency induction heating or heating furnaces may also be used, and the optimal method is chosen based on the size, shape, and quantity of the parts to be joined. I am looking forward to trying various materials in the future. Furthermore, I can offer proposals that include not only joining but also shape processing, so please feel free to consult with me. ■ Cross-sectional images Cu + Cu (Copper + Copper) W + Cu (Tungsten + Copper) Mo + Cu (Molybdenum + Copper) Mo + Mo (Molybdenum + Molybdenum)

We have ultra-high temperature heat treatment furnaces! We will address your challenges with our years of heat treatment technology. Leave the coating and brazing of metals and ceramics to us!

We would like to introduce some coating examples. This one is tungsten coated with alumina (Al2O3). To enhance thermal efficiency, we have further coated the alumina coating with (alumina + tungsten). This is a component inside the cathode used in electric propulsion systems for small satellites, but it seems to be used in other applications as well. Our company has a well-equipped heat treatment furnace, and in addition to coating, we respond to various requests such as brazing and material development. We also accept commissioned processing from research and development, so if you have any concerns, please feel free to consult us first. ◆ We will propose solutions utilizing our heat treatment furnace tailored to your needs: - Coating - Brazing - Functional material development - Sintering - Residual stress removal - Crystal grain size control - Oxide removal - Contamination removal - Degassing - De-greasing ...and more.

Metals and ceramics: We will propose the optimal heat treatment tailored to your needs!

Generally, high-temperature heat treatment takes several hours, which can be costly and time-consuming. Gakuseki Electric has been conducting heat treatment of high melting point metals and ceramics, including tungsten. In particular, to quickly and efficiently perform heat treatment for small, low-volume, and diverse products, we have repeatedly conducted various experiments and successfully developed a high-speed high-temperature vacuum furnace capable of reaching approximately 2700°C. With this equipment, ■2500°C for 30 minutes ⇒ The entire process from the start of heating to cooling down is completed in about 2 hours! We have achieved efficiency and cost reduction. Additionally, substances that cannot be completely removed in general furnaces can also be heated and removed. ーーー We also accommodate various high-temperature heat treatments, including multi-atmosphere sintering furnaces and forming gas flushing furnaces. Through these high-temperature heat treatments, it is possible to ultimately prevent the residue and contamination of impurities. With decades of accumulated experience and know-how in heat treatment, please leave the heat treatment of metals to Gakuseki Electric. ーーー

From prototyping to mass production of difficult-to-machine materials such as tungsten, molybdenum, and tantalum.

We perform precision machining of difficult-to-cut and difficult-to-process materials such as tungsten, molybdenum, and tantalum. For mass production, we automate the process using feeding machines, while for prototypes ranging from one to a few pieces, we respond quickly with manual operations. In particular, precision machining of small products with tolerances in the micron or millimeter range is our specialty. ◆ Precision machining using NC lathes and other machine tools We utilize NC lathes, MC multi-tasking machines, milling machines, centerless grinders, automatic precision cutting machines, wire-cut and electrical discharge machines, automatic surface grinders, injection molding machines, extrusion molding machines, and presses. ◆ In-house automatic assembly and processing machines We have a wide range of in-house developed fully automatic machines, including fully automatic hot press machines, automatic heater coil assembly machines, and fully automatic electrode assembly machines. Gakuseki Electric often takes on the manufacturing of products that other companies are reluctant or unable to produce. If there are no machines available in the market for manufacturing, we design and build our own processing machines. ◆ Processing - Cutting - Machining - Milling - Cutting - Tapering - Drilling *Sizes, precision, and handled materials are detailed in the "Basic Information" section.

■Background of Development For many years, we have been commercializing various shapes of filaments using tungsten. However, in recent years, with advancements in science and technology, customer needs have diversified, making it increasingly difficult to meet their demands with tungsten alone. ■Overview of Development With the aim of enhancing the functionality of filaments, examples of customer requests included "insulation," "corrosion resistance," and "low work function." In response, we have incorporated the following into our filaments: ● Aluminum oxide (alumina) for [insulation] (Coating alumina onto tungsten coils) ● Yttrium oxide (yttria) to provide [corrosion resistance] and [low work function], successfully enhancing functionality. (Coating yttria (Y203) onto the filaments) ■Details of Development In developing the coating technology, we adopted a certain method. While it is a common approach, it is based on [our unique equipment and manufacturing process]. We optimize factors such as particle size, mixing ratio, and film thickness through experimental investigation, but this is not easy. Ultimately, the number of experiments has reached into the thousands, and we continue to work on quality improvement.

■Development of Molybdenum-Ruthenium Filler Metal This filler metal is used for joining (brazing) high melting point metals due to its high melting point, but it is not commercially available, so it was necessary to procure the materials independently. Using the developed filler metal, we attempted brazing between tungsten pieces. *The left side of the photo shows porous tungsten.* Photo 1: Observed by a CCD camera. This is a failed example where a large gap occurred at the joint. In reality, it was quite difficult to achieve a good result. Photo 2: Successful example! (The joint is in the center of the photo.) Photo 3: Reflection electron image by SEM. It can be seen that the joint is made without gaps due to the filler metal. Photo 4: Element mapping. The joint area has become clear. Perhaps due to its porous nature, the filler metal seems to have diffused on the left side. ◆Our company possesses a super high-temperature heat treatment furnace capable of up to [2700°C]. We have numerous furnaces that can accommodate various atmospheres and offer solutions utilizing heat treatment furnaces tailored to your needs. - Coating - Brazing - Functional material development - Sintering - Residual stress removal - Grain size control - Oxide removal - Contamination removal - Degassing - De-greasing ...and more.

Utilizing the properties of Ni-Ti alloy, along with a safe coating that can be used within the body.

Now, let me introduce the "Ni-Ti Coating Coil." It may sound a bit confusing as I write this, but here are the processes involved: (1) Coiling of Ni-Ti (high elasticity, shape memory alloy) (2) Shape memory treatment (500°C) (3) PTFE coating The Ni-Ti alloy is known for its superelasticity, and we plan to develop products that leverage this characteristic. By applying a PTFE coating, the design is safe for insertion into the body. Additionally, PTFE allows for color selection based on purpose (please consult for color variations). As a side note, the current sample is intended for orthodontic purposes, and there was a request for a slightly yellowish white instead of a bright white, as the latter would be too conspicuous (though it would be a perfect match for Coach Shinjo). This also depends on user preferences, but in Western countries, due to high medical costs, there is a perception that "orthodontics = wealth," leading to opinions that some may want it to stand out more.
