This technology has a wide range of applications. It can be said that as long as the basic material is metal, it can be used anywhere with friction. Ceramic strengthening can greatly improve the hardness, toughness, wear resistance and corrosion resistance of tools, tools and dies, and the service life can be increased by more than 2 times. The market application shows that the ceramic piston ring of automobile, ship, train, motorcycle and other engines has obvious fuel-saving effect, which prolongs the interval between overhauls, purifies the exhaust emission, improves the combustion performance of the engine, and at the same time plays the role of internal purification, which has considerable economic and social environmental benefits. With the development of China's economy, especially after China's entry into WTO, China will enforce Euro II emission standards, and China will meet Euro III emission standards in the 2008 Olympic Games. These are opportunities and catalysts for this technology and products to occupy the market. The implementation of this series of high automobile emission standards will not only lead to the overall acceleration of China automobile industry, but also make the thin-film ceramic strengthened surface technology widely popularized and applied.
Market charm of strengthening technology of metal composite ceramics
□ Chairman and General Manager Jiang Wei
Hefei University of Technology Metal Composite Ceramics High-tech Co., Ltd. was established in 1999, which was jointly funded by Anhui Tianhui Group Corporation and Hefei University of Technology. The project of "Thin Film Ceramics Strengthening Metal Surface Technology" is the first choice of the company, which conforms to the industrial development direction encouraged and supported by the state, can fully reflect the national industrial value and has high maturity. This technology won the national invention patent and the third prize of national invention. It was included by 199 1 in the "World Invention Patents" database of the United States and won the first place in the "Ford Fund" evaluation organized by the National Natural Science Foundation. It is a national key achievement popularization and application project of the State Science and Technology Commission during the Eighth Five-Year Plan and the Ninth Five-Year Plan. Hefei University of Technology provides effective technical support for the expansion of this technology in the production process and application field of enterprises; Anhui Tianhui Group is well funded and has rich successful experience in market development, capital operation and enterprise management. As the patent owner of this high-tech company, it is inevitable that this company will closely combine technology with production.
The surface strengthening technology of thin-film ceramics is to generate a cermet thin film with network structure and bidirectional microcrystal diffusion on the metal surface by using ultra-fine particle low-temperature plasma chemical vapor deposition technology. It is a new functional material with inclined gradient, which has the advantages of both metal and ceramic, and has catalytic effect on ch and CO. After ceramic infiltration, the surface hardness increases and the service life is prolonged. In the comparison test of YZ 104 15 truck idling emission pollutants, CO is 2.3% and 0.6% respectively, and HC is 6 17ppm and 93ppm respectively, which reduces CO by 73.9% and HC by 84.9%. This technology has a wide range of applications. It can be said that as long as the basic material is metal, it can be used anywhere with friction. Ceramic strengthening can greatly improve the hardness, toughness, wear resistance and corrosion resistance of tools, tools and dies, and the service life can be increased by more than 2 times. The market application shows that the ceramic piston ring of automobile, ship, train, motorcycle and other engines has obvious fuel-saving effect, which prolongs the interval between overhauls, purifies the exhaust emission, improves the combustion performance of the engine, and at the same time plays the role of internal purification, which has considerable economic and social environmental benefits. With the development of China's economy, especially after China's entry into WTO, China will enforce Euro II emission standards, and China will meet Euro III emission standards in the 2008 Olympic Games. These are opportunities and catalysts for this technology and products to occupy the market. The implementation of this series of high automobile emission standards will not only lead to the overall acceleration of China automobile industry, but also make the thin-film ceramic strengthened surface technology widely popularized and applied.
This technology has passed the bench test of more than a dozen related manufacturers such as No.2 Automobile Technology Center, Changsha Engine Factory and Yulin Diesel Engine Factory. Liuzhou Automobile Engine Factory and Changsha Jacky Power Parts Factory have adopted a large number of thin film ceramic piston rings on 4 105 and 6 105GB engines. 1997 12 17 was popularized and applied on diesel locomotives by the Ministry of Railways; Shanghai Bus No.1 Company, Baoshan Bus Company, Wuhan Bus Company, Hefei Bus Company and Chongqing Bus Company are also used in batches. The concentrated reaction of users is that the service life of products is generally extended. For example, the locomotive depot of Shanghai Railway Sub-bureau installed composite membrane ceramic piston rings on diesel locomotives. The application results show that it not only improves the service life, but also enhances the sealing performance of the cylinder and improves the combustion performance, thus achieving the purpose of saving fuel and reducing mechanical wear. They have been used on imported NDI and domestic Dongfeng 4 locomotives successively, and have achieved great success. According to industry analysis, diesel locomotives equipped with thin-film ceramic piston rings can save fuel costs 1 10,000 yuan per month. If all 20,000 locomotives in China are fitted with this ring, it will save 2 billion yuan every year.
Practice has proved that only through industrialization can scientific and technological achievements give full play to their social and economic benefits.
The future business direction of the company is to take ceramic permeable piston ring as the leading product, and expand the production scale and improve the economic benefit through the way of "processing with supplied materials -OEM- merger and expansion". We will strive to expand the application scope of this patented technology, such as tools, molds and other parts of metal friction pairs, and at the same time strengthen the research and test work in the application field of metal composite ceramic products. Only by always grasping the high-tech content of enterprises, always adhering to the development direction of advanced productive forces, relying on scientific and technological research results as technical backing, and relying on the technological innovation and pioneering spirit of all employees, the company's economic benefits and business scale will be improved just around the corner, and the company will enter a new stage of great development.
