China fills the world gap in the field of composite materials

if there is a need to replace the gasket, the largest civil high gravity combustion synthesis device in the world has been successfully trial produced in Huayuankou economic zone. This technology, jointly developed by the Institute of physical and chemical technology of the Chinese Academy of Sciences and Dalian hanton Industrial Company, has filled the world gap in the field of metal ceramic composites

at 3:00 p.m. on November 27, in the production workshop of Dalian hanton Industrial Company, an alloy blank with a diameter of 200 mm and a thickness of 10 mm was successfully produced by the research group. It is also synthesized by centrifugal hypergravity infiltration technology. The first tungsten nickel carbide gradient cemented carbide material will be used to process mining drilling tools and wear-resistant workpieces

liuguanghua, associate researcher of the Institute of physics and chemistry of the Chinese Academy of Sciences: "the performance indicators of the products now produced are close to those of commercial products. The main work to be done later is to improve the stability of the process and can be produced repeatedly and with high quality."

after two years of technical research, the Institute of physics and chemistry of the Chinese Academy of Sciences used this high gravity centrifugal equipment. In 2010, the world medical device industry was composed of 27000 medical device companies. Five batches of cermet alloy blanks were manufactured successively, which were easy to absorb moisture. The high gravity infiltration technology synthesized by cermet materials was successfully industrialized. Compared with the traditional powder metallurgy technology, it has obvious energy-saving advantages

liguobin, director of the ceramic engineering center of Dalian hanton Industrial Company: "in terms of power supply, our whole set of equipment up to now, such a large device is only 10 kilowatts (energy consumption)."

it is understood that this project has been included in the "863 Program" of the Ministry of science and technology and the international thermonuclear fusion supporting materials project. It is expected to synthesize oversized alloys early next year for domestic thermonuclear fusion reactor experiments
