Russia and Poland jointly developed composite materials with extremely high hardness

scientists from the Institute of high pressure physics of the Russian Academy of Sciences and the Polish High Pressure Research Center recently synthesized new composite materials with hardness close to diamond and wear resistance higher than diamond

according to the Russian "news" report, scientists found that the hardness of each crystal surface of diamond single crystal is different, and its compressive resistance is 70 billion to 10 billion Newtons per square meter in recent two years. However, cutting tools made of this material will gradually expand cracks in the process of wear. In order to overcome this defect, the scientific research team composed of Russian and polish experts synthesized new composite materials with nano diamond particles and powdered silicon carbide as raw materials

Russian wave experts pointed out that when the explosive containing graphite particles explodes, the high pressure and high temperature generated will instantly turn the graphite particles into diamonds about 10 nm in size. Using the feedback signals of various parameters to form a closed-loop control system, some analysts believe that in order to realize the automatic control of all vulnerable parts in the experiment 1: the sensor process, and achieve the corresponding control accuracy particles. Put these diamond particles and powdered silicon carbide into the annular high-pressure chamber, make the pressure in the high-pressure chamber reach 8billion pascals, and raise the temperature to about 2000 degrees Celsius, then a new composite material with dense structure can be formed. The diamond particles in the new material are firmly combined with the silicon carbide interlayer, which can withstand a pressure of 80billion Newtons per square meter in all directions. Its compact structure can prevent small cracks from gradually expanding in the wear process

Russian Polish experts said that in the next stage, they will conduct research on the application of new materials
