The metal cryogenic treatment originated in Switzerland for more than a hundred years. At that time, people found that tools refrigerated in ice and snow can be used for a longer time. Switzerland, watches and Gillette blades were the beneficiaries of this process at that time. Beginning in the 1960s, the United States, the Soviet Union, Japan and other countries began to study the metal cryogenic technology. A large number of tests found that cryogenic treatment effectively extended the life of the tool. In the 1980s, several cryogenic companies in the United States, such as 3xistruments & Toling, Material Improvement, and Ame cry, etc., cold-treated tools, abrasives, gears, special springs, cemented carbide, high-speed steel, and cobalt-based alloys, respectively. Experimental results show that cryogenic treatment equipment 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 carried out 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 full research and analysis of high-speed steel, die steel, cemented carbide and other materials. The research shows that cryogenic treatment equipment can improve the wear resistance, toughness, hardness, dimensional stability and corrosion resistance of these materials. Sex plays a different role.
