Cryogenic treatment refers to materials that need to be processed in an environment of -190°C to -230°C. Suitable for all metal or non-metal materials, such as alloys, carbides, plastics (nylon and Teflon), aluminum, ceramics, etc.
Ultra-cryogenic technology: When the metal is hardened by heat treatment to the cooling process, the alloy and carbon are dissolved and combined and diffused to form austenite. During the cooling process, martensite is formed due to low temperature compression. Martensite), and because the final transformation point (Mf) of martensite is very low. The hardness, wear resistance and service life of the metal, and the volume change caused by the instability of austenite is prone to structural transformation, causing metal fragmentation. Furthermore, there are many physical properties, especially thermal properties and magnetic properties.
Metal cryogenic treatment originated in Switzerland for more than one hundred years. At that time, it was discovered that tools that had been refrigerated in ice and snow could last longer. Swiss army knives, clocks, and Gillette blades were all beneficiaries of this technique at that time. Beginning in the 1960s, the United States, the Soviet Union, Japan and other countries began to study metal cryogenic technology. A large number of experiments found that cryogenic treatment effectively extended the life of tools. In the 1980s, several specialized cryogenic companies in the United States, such as 3xistruments&Toling, Material Improvement, and Ame Cry, carried out operations on cutting tools, abrasive tools, gears, special springs, cemented carbide, high-speed steel, and cobalt-based alloys. Cold treatment, experimental results show that cryogenic treatment has a significant effect on the service life of the above-mentioned material parts, which can be increased by 5 to 10 times.
Domestic research was launched in the middle of the 20th century, using alcohol + dry ice to conduct dimensional stability tests and applications of molds, measuring tools, and tools. In the 1990s, various institutes began to conduct sufficient research and analysis on high-speed steel, die steel, cemented carbide and other materials. Research has shown that cryogenic treatment can improve the wear resistance, toughness, hardness, dimensional stability, and corrosion resistance of these materials. All play a role in varying degrees.
