The independent innovation of nano-coating technology on the surface of superhard tools has yielded fruitful results

On November 21, the workshop on nano coating treatment equipment and process technology of domestic alternative superhard materials (tools) was held in Beijing, sponsored by the Special Committee of Science and Technology Service Talent Employment of China Productivity Promotion Center Association. Liu Yulan, former Director of the Office of Major Projects of the Ministry of Science and Technology; Jia Yinsong, former Deputy Director of the Department of Raw Materials of the Ministry of Industry and Information Technology; Deng Fuling, Director of the Institute of Superhard Tool Materials of China University of Mining and Technology (Beijing); Liu Ruiping, Deputy Director of the Institute of Science and Technology of China University of Mining and Technology (Beijing); Wang Xuemin, Professor of the Collaborative Innovation Center of Common Technology of Iron and Steel of the University of Science and Technology Beijing; New Material Technology of the University of Science and Technology Beijing Wei Junjun, Researcher of the Research Institute, Deng Wenli, assistant researcher of the National Key Laboratory of Friction and Wear, Department of Mechanics, Tsinghua University, and Zhang Zhanjun, chairman of Guangdong Juliang New Materials Co., LTD., attended the meeting. The participants conducted in-depth discussions on topics related to the domestic replacement of nano-coatings on the surface of superhard materials (tools). Tsinghua University, China University of Mining and Technology (Beijing) and Guangdong Juliang New Materials Co., Ltd. signed a strategic cooperation agreement on the site, aiming to jointly promote the innovative development of domestic alternative superhard materials (tools) surface nano coating technology.

With the continuous progress of science and technology and the continuous development of material engineering technology, the production technology of superhard tools is also constantly improving, and the new superhard tool materials and manufacturing technology not only improves the performance indicators of superhard tools, but also effectively controls the production cost, making the application of superhard tools in the field of industrial manufacturing increasingly widespread. In recent years, China has successively launched relevant policy documents to vigorously encourage the development of high-end equipment and new materials. In this context, it is of extraordinary significance to discuss the exchange of domestic alternative superhard materials (tools) surface nano coating treatment equipment and technology.

China University of Mining and Technology (Beijing) Superhard tool Materials Research Institute developed the first set of four-target magnetron sputtering equipment in China in Guangdong Poly New Materials Research and Development Center, and cooperated with the coating process test of related products, and put into industrial production after meeting the performance requirements.

It is understood that the Institute of Superhard Tool Materials of China University of Mining and Technology (Beijing) on the basis of the successful market development of multi-layer nano-superhard blade, using the super-hard, wear-resistant and super-slippery properties of nano-multilayer superhard coating, can develop high-precision tooling and mechanical wear-resistant devices and other products, such as multi-layer nano-diamond-like coating drill bits, TiCrN gear hobs and so on. In the future, it will also use the biocompatibility, corrosion resistance and ultra-low friction coefficient of diamond-like diamond to develop diamond-like artificial bone and artificial joint materials and related products; By using the superslippery and superhydrophobic properties of nano-multilayer superhard coatings, nano-multilayer superhard coatings and related products for aerospace and infrared guidance optical Windows can be developed.

The rapid development of modern precision manufacturing has brought continuous growth to the superhard material tool, and its compound annual growth rate is expected to reach about 20%, and the nano-multilayer superhard mold will break through the growth rate of 20%. The scale of the superhard tool industry will further expand rapidly, and the future competitiveness of the domestic industry is expected to be significantly improved in the international market.
