Application of boron carbide structure as material

1) Application of boron carbide structure as material
In the industrial application field of boron carbide materials, boron carbide is first used as an abrasive, from powder with a particle size of 1um to pellets with a diameter of 10mm. For example, boron carbide is used as an abrasive for other hard materials such as cemented carbide and engineering ceramics. The abrasive materials used in polishing, grinding or crushing processes can replace the original diamond materials, which can greatly reduce the cost of the grinding process. In addition, wear-resistant and corrosion-resistant boron carbide devices can be produced through non-powder metallurgy. Good application results have been achieved in many fields. For example, boron carbide devices can form pneumatic slide valves, hot extrusion dies, and journal bearings in cooling systems of atomic power plants; they are used for corrosion resistance and friction and wear resistance in ceramic gas turbines; Sandblasting nozzles and high-pressure water jet cutting nozzles; boron carbide is also a high-performance gas bearing material in long-life gyroscopes; because boron carbide is stable to molten iron and has good thermal conductivity, it can be used in continuous casting molds in the mechanical industry; and because boron carbide material It can resist strong acid corrosion and fatigue, and can be used in the flow pattern of rocket liquid engine fuel. The shaft tip is also externally coated with boron carbide material to make cutting edges.
