5 Key application areas of development
With the continuous emergence of high-hard and tough heat-resistant alloys, carbon fiber and other composite difficult-to-machine materials, energy-saving emission reduction, environmental protection production requirements are constantly upgrading, new process technology continues to innovate and apply, high-speed, ultra-high-speed, high-efficiency, precision, ultra-precision, high Reliability, long life and green production have become new requirements in the field of processing and manufacturing. The performance requirements of processing tools are also increasing. Super-hard materials with extreme performance and various processing tools meet this demand. The field of technical processing and manufacturing provides a rare means of processing. Superhard materials products have been increasingly applied to various fields of the national economy, including aerospace, defense and military, electronic information, clean energy, automobiles, home appliances, bioengineering, building materials and other national security and strategic emerging industries. And other fields. The industry will break through a number of key technologies in these key application areas.
5.1 Aerospace field
In the aerospace field, more and more difficult-to-machine materials such as titanium alloys, superalloys, and carbon fiber composites are used, and their high-efficiency processing problems are outstanding. To support the development of the aerospace industry, the superhard materials industry must break through the technical difficulties and develop and provide high-precision and high-efficiency cutting and polishing tools and stealth anti-corrosion materials for this field. At present, the domestic use of traditional abrasive tools and tools for processing, there are problems such as low processing efficiency, fast tool loss, and low precision of machined workpieces. Foreign countries have adopted superhard material tools instead of traditional tools to efficiently and precisely process these materials. At the end of the “Thirteenth Five-Year Plan” period, domestic superhard material abrasive tools and tools (including composite superhard materials for tools) should be applied in a large area in this field, and the market share should strive to reach more than 50%.
5.2 Defence Military Industry
The national defense industry has special requirements such as super large, super micro, super precision, high reliability and long life. The materials used are also special. The superhard materials industry has the responsibility and obligation to continuously develop special cutting and polishing tools and stealth anticorrosion for these fields. Materials, such as aircraft engine, aircraft engine, aircraft brake pads, missile fairing and other special processing tools, military aircraft and missiles and other stealth anti-corrosion materials to meet the needs of national defense construction.
5.3 Electronic Information Field
The manufacture of semiconductor chips uses diamond abrasive tools to achieve high-efficiency and ultra-precision processing of nano-level precision and surface roughness of silicon material on the back side of the chip. The diamond ultra-thin grinding wheel is used for cutting and packaging; in order to further improve production efficiency, more and more monolithic pieces are used. The processing of diamond ultra-thin grinding wheel is changed into multiple pieces or even hundreds of grinding wheels. During the “Thirteenth Five-Year Plan” period, we should continue to improve the level of such tools and replace imported products more broadly. At the end of the period, we should be able to provide complete sets of fine precision grinding and polishing tools for this field until we provide cutting and polishing solutions.
5.4 Clean Energy Sector
Hydropower, wind power, nuclear power, photovoltaic power generation, LED lighting, etc. all belong to the field of clean energy. Any kind of clean energy uses super-hard materials tools. Among them, the diamond-cutting and diamond-lighting industries use the fine-cut precision tools. At present, the import tools of developed countries in these areas account for the majority, and domestic tools are in a secondary position. During the “Thirteenth Five-Year Plan” period, the localization of kit technology should be realized. At the end of the period, domestic tools should be in a dominant position, and the domestic market share will reach 70%.
5.5 Automotive manufacturing
Ultra-high-speed grinding technology has been promoted and applied in the manufacture of key automotive parts. In order to avoid the excessive load on the machine tool spindle and the excessive radial expansion of the base body under ultra-high speed conditions, the ultra-high-speed CBN grinding wheel is required to achieve light weight; the camshaft of one of the key components of the automobile engine, There is a tendency to develop from a single material to a complete assembly (spindle and cam are different materials), and it is required that the CBN grinding wheel realizes high-speed, ultra-high-speed and high-efficiency processing of several millimeters of different materials in one clamping. The double-end grinding of the automobile connecting rod adopts the ceramic CBN grinding wheel instead of the ordinary grinding tool processing, which not only greatly improves the grinding efficiency, but also realizes the no-trimming processing; the blank of the automobile engine casing casting adopts the super-hard abrasive tool instead of the ordinary grinding tool to realize the low Dust efficient deburring processing. At the end of the “Thirteenth Five-Year Plan” period, domestic superhard material abrasive tools and tools (including composite superhard materials for tools) should be widely used in this field.
5.6 Household appliance manufacturing
The field of home appliances is also a traditional service field for super-hard materials tools. With the improvement of people's living standards, higher requirements are placed on the quality of home appliances. Energy conservation, environmental protection, low noise and long life are the higher goals pursued by the home appliance industry. Constantly appearing, such as the air-conditioning, the main components of the refrigerator compressor cylinder liner, the fixed-face grinding technology of the fixed abrasive for the sliding sheet replaces the traditional processing technology, and puts the flatness, parallelism and durability of the abrasive tool more than the ordinary grinding With orders of several orders of magnitude higher. During the “13th Five-Year Plan”, we will continue to strengthen the tracking of the industry's increasingly high-tech requirements, break through the high-end product manufacturing technology in this field and provide new sets of grinding services.
5.7 Functional applications such as bioengineering
Using the biocompatibility, low toxicity, and fluorescence effects of nanodiamonds, it has become increasingly prominent in biomedical fields such as drug carrier materials, bioimaging tools, proteomics mass spectrometry, fluorescent probe materials, and quantum probes. The more important role; diamond membrane biosensor is the combination of biologically active materials (enzymes, proteins, DNA, antibodies, antigens, biofilms, etc.) with physical and chemical sensors, mainly used in biological sciences, clinical medicine, bioengineering and Environmental protection and other fields.
Nanodiamond particles are much smaller than infrared and radar wavelengths, and their transmittance for this wavelength is much stronger than conventional materials, which greatly reduces the reflectivity of the wave; in addition, its specific surface area is larger than conventional coarse powder. Four orders of magnitude, the absorption rate of infrared light and electromagnetic waves is much larger than that of conventional materials, making the reflected signals received by infrared detectors and radars weak, so it is difficult to find the target to be detected and play a stealth role. Countries such as the United States have applied ultra-fine diamond absorbing materials to stealth aircraft many years ago. China is also strongly promoting this technology under the support of the super-hard materials industry.
In terms of environmental protection, the use of a boron-doped diamond electrode with a wide electrochemical potential window, low background current, excellent chemical stability and strong resistance to surface contamination has unparalleled superior properties in conventional wastewater treatment.
In terms of optics, the diamond film has the advantages of high transmittance, high hardness, low friction coefficient and good chemical stability, and is used as a variety of optical materials such as silicon, germanium, glass, zinc sulfide, magnesium fluoride, and cadmium telluride. Anti-wear/protective film of mercury, potassium chloride, etc., which is resistant to abrasion, corrosion, dehydration and oxidation, has been applied to solar silicon cells, high-power CO2 laser windows, periscope infrared (IR) windows, Aircraft front view infrared window, missile hood window and aerospace detector.
In addition, diamond has unparalleled superiority in many aspects such as acoustics, thermals, electricity, etc., and has been applied in the early stage. During the “Thirteenth Five-Year Plan” period, it is necessary to strengthen the development of these functional application areas, strive to reduce costs, expand the application, and lay a good foundation for the development of high technology.
5.8 Advanced Tool Manufacturing
The field of high-end tool manufacturing is the traditional application field of diamond tools, but new high-end advanced tools are constantly appearing, and the requirements for super-hard material grinding wheels are constantly increasing. For example, rotary solid carbide tools are processed. At present, diamond grinding wheels are widely used in foreign countries. The high-efficiency forming grinding of the main groove is completed in one time, and the processing efficiency is continuously pursued. In addition, as the precision of the tool is continuously improved, the self-sharpness and wear resistance of the grinding wheel are also put forward higher requirements. During the “Thirteenth Five-Year Plan” period, we will continue to strengthen the high-tech requirements of the tracking tool industry, break through the high-end product manufacturing technology in this field and provide complete sets of grinding services for new tools and complex combination tools.
5.9 Oil and gas field and mineral exploration and mining
Break through the complex hard formation with a depth of more than 4,000 meters, oriented and horizontal wells, and PDC synthesis and bit manufacturing technology for exploration and mining of offshore oil and gas fields.
5.10 Building materials field
The building sector uses sawing and drilling tools to consolidate its position in the world's advanced level, develop high-tech products with higher efficiency, longer life and lower processing noise, and further expand the professional market share of developed countries.
Diamond mining tools in stone mines have developed more energy-saving and environmentally-friendly products such as wire saws and chain saws for different mines, improving the rate of raw materials and reducing waste emissions.
Stone, ceramic wall and floor tile processing diamond tooling, especially fine grinding and polishing tools, to minimize or eliminate the use of typical high energy consumption and heavy pollution resource silicon carbide grinding blocks, to achieve the purpose of energy saving and emission reduction of wall and floor tiles production.
