What is cubic boron nitride? The second hard artificial abrasive, second only to diamond, is widely used in superhard tools, heat sink materials, high temperature semiconductors, etc. Although it is a "second child", the future is immeasurable. At the recent investment and financing meeting, Hangzhou Tianzhu Technology Co., Ltd. took out the cubic boron nitride film, so that you can use the diamond drill, you can also take the porcelain work, as long as a film is coated, the knife can cut iron and mud; At the same time, it can also change the thermal energy of the LED lamp to light energy, and a thin film can save several Three Gorges Dams.
Perhaps you don't know that although diamond is high in hardness, it is inherently fragile. Oxidation occurs at 500-700 degrees Celsius. When the temperature reaches 700 degrees Celsius, it will begin to dissolve in iron. So who can cut iron? Yang Hangsheng, the person in charge of Tianzhu Technology, told the reporter: "As long as you have a layer of cubic boron nitride film with high hardness and high temperature resistance on the outside of the tool." This tool life is 10 times higher than that of cemented carbide tools. 20 times ceramic tools. The cutting speed can be increased by 8 times compared with cemented carbide tools. The maximum temperature for maintaining cutting performance is also nearly 1000 degrees higher than that of high-speed steel, and dry cutting can be performed without cutting fluid within a certain range.
In addition to being plated outside the tool, cubic boron nitride can be plated on the outer layer of the LED lamp. The function is to help the thermal energy of the LED lamp to become light energy, bring the heat out of the chip, and avoid excessive heat damage to the chip material, which means that the heat dissipation problem of the LED can be fundamentally solved.
"Our ordinary incandescent lamps, only 20% of the energy is converted into light, and the remaining 80% is converted into heat. The global LED lighting application market is huge, and it is expected to reach 62.5 billion US dollars in 2014, then our cube The boron nitride market can be said to be high in water and has a bright future." Yang Hangsheng said, "If one third of the country's street lamps are replaced with LED lights, it can save several generations of power generation of the Three Gorges Dam. This part of the power generation is used in other fields. Can add huge economic benefits."
