Looking for development direction, superhard materials must open up new markets.
1. Develop superhard materials for high and new technology products.
(1) The core technology of solar photovoltaic industry lies in the solar cell, that is, the slicing technology of monocrystalline silicon and polycrystalline silicon. The diamond used in diamond wire saw or ultra-thin slice cutting (making semiconductor chip) has special requirements. They must master its production technology.
(2) Using diamond as heat sink, thermistor, microwave device, high power integrated circuit, laser and so on, special diamond is needed in thermal management materials.
(3) In the military industry, the use of diamonds with good light transmission, from ultraviolet to far infrared transparent, can be used as cruise missiles and other lens materials, but also requires the use of special diamonds.
(4) nano diamond has its special properties, which is used in defense advanced science as invisible material.
In short, superhard materials in high and new technology, the application of a wide range, high requirements, good prospects, we must strive to develop new superhard materials and products to meet market demand.
2, combine superhard materials with cemented carbide tools to develop products with high technology content.
There are many production processes for the combination of superhard materials and cemented carbides, such as electroplating, sintering, rolling and compounding. For example, the composite of superhard alloy and superhard material forms a new material, which greatly improves the hardness, strength and wear resistance of the alloy, and makes it into composite sheet, ball tooth and pick. Its service life is several hundred times longer than that of the cemented carbide bit. Oil drilling must be carried out in a deep well below three thousand meters. In the future, the shield components used in high-speed railway, subway and tunnel in our country will also use superhard materials, and the service life of shield machine in our country is still very short.
3. The combination of superhard materials and abrasives will soon replace ordinary abrasive tools.
Although the price of ordinary abrasives is cheap, but environmental pollution, backward production technology, can not meet the market demand, but also the national restrictions of products. Since 2010, several powerful domestic enterprises have begun to use diamond instead of silicon carbide and cubic boron nitride instead of corundum to produce grinding heads, discs, grinding blocks, grinding wheels, abrasive belts and other products. Their performance and service life have been greatly improved, and they are in line with environmental protection policies. Because of the high price of superhard abrasives, the general user is difficult to accept, slow promotion, and now the price has been reduced, superhard Abrasives have great prospects for development, some statistics, only the consumption of superhard grinding wheels accounted for 1/4 of the total consumption of superhard abrasives. It can be seen that the development of superhard Abrasives has brought unlimited business opportunities to superhard materials.
At present, China has included superhard materials, some alloy tools and abrasives in new and high technology industries. The superhard industry will have better development space in the future. As long as we do a good job in changing products from output to quality, varieties from comprehensive products to high-tech products, and strive to develop high-tech products, we will certainly increase the economic benefits of enterprises, countries and the world.
