In July 1990, the first International Conference on nanoscience and technology was held in Baltimore, USA, marking the formal birth of nanoscience and technology. The conference officially announced nanomaterial science as a new branch of material science.
In 1999, nanotechnology went to the market, and the total annual turnover of products based on nanotechnology reached up to 50 billion dollars. Some countries formulated relevant strategies or plans to invest huge sums of money to seize the strategic height of nanotechnology. Japan set up the research center of nano materials, the nanotechnology included in the new 5 year plan key basic technology research; Germany established nanotechnology research network; the United States will be regarded as the core of nano plan the next industrial revolution; Chinese will also be listed as China nano science and technology "973 plan".
In 2001, a branch of technology derived from nanotechnology, micro and nano application technology, was derived from nanotechnology. The application of micro nano technology in developed countries based on the material field has been applied and achieved amazing results, especially the application of nanotechnology to produce many microcrystalline alloy material, is having a profound impact on human, has completely changed people's way of thinking.
In 2005, the China micrometer and nanotechnology society was formally established, marking the start of China's micro and nano application technology and meeting the needs of functional materials in the same starting line with developed countries.
A member of Chinese micron nanotechnology researchers learn to use the micro nanotechnology in the field of friction reduction of special alloy materials, has developed a microcrystalline alloy material to meet the special needs of certain individual properties, such as nickel based light alloy, magnesium based ceramics used in aero engine high temperature ceramics, high reliability requirements of silver alloy microcrystalline alloy. The special microcrystalline bearing material not only fills the gap of the friction reducing material in China, but also keeps pace with the world's Microcrystalline Alloy Technology from the single performance of the material.
In 2009, the experts of Shenyang Institute of Metal Research Institute, Shenyang Research Institute of Foundry, ShenYang Ligong University and other micro nanotechnology research, carry out research joint research; technology developed a set of micro alloying treatment and low temperature quenching combined casting (commonly known as the three time melting process method), the zinc base alloy ceramics preparation; existing four kinds of zinc based alloy ceramic materials have been realized mass production in China, including a microcrystalline zinc base alloy LZA3805 ultra low friction coefficient, with microcrystalline zinc base alloy LZA4008 large PV value characteristics of microcrystalline zinc base alloy LZA4205 has super wear resistance, has good anti impact properties of microcrystalline zinc base alloy LZA4510 etc..
Zinc base microcrystalline alloy can meet the characteristics of special requirements of individual performance, is an important symbol different from traditional ordinary antifriction alloy, for antifriction material customized production equipment manufacturing industry, to meet the personalized needs of manufacturing equipment, provides a powerful guarantee for the realization of equipment manufacturing with high efficiency, high precision and high reliability. Low cost etc..
In 2010, the zinc based alloy manufacturing ceramic bearing, sleeve, worm, plate, nut etc. series of antifriction products, has succeeded in forging equipment manufacturing industry, CNC machine tool manufacturing industry, by gearbox manufacturing industry, heavy mining equipment manufacturing industry, engineering machinery manufacturing industry has been applied.
Zinc based microcrystalline alloys successfully replace the traditional friction reducing alloys and new antifriction alloy products with their high reliability and stability. They have achieved good social benefits and huge economic benefits, indicating that the development of zinc based alloys in China has entered the era of "Microcrystalline Alloy".
