| titleOfInvention | Method of obtaining compounded ceramic material |
| abstract | The invention relates to the technology of silicon carbide-based ceramic composite materials and can be used to obtain high-strength, crack-resistant materials in mechanical engineering and power engineering. mining industry and other areas of technology. The invention is aimed at increasing the crack resistance. strength and relative deformation. For this, a porous carcass is formed by sintering in vacuum, pressing silicon carbide powder of a fraction of 40-56 µm at a temperature of 1900-2000 ° C for 5-7 hours. The carcass is impregnated with aluminum melt in a vacuum, the partial oxidation of aluminum is carried out by oxidizing the surface of the impregnated frame in the stream of oxygen with a flow rate of 0.5-1.5 l / min, at a temperature of 0.95-0.99 from the melting point of aluminum for 0.5-2 hours after oxidation, gas-static compression is additionally carried out at a pressure of 100-200 MPa at a temperature of 0.95-0.99 from the melting temperature of alum Inini followed by cooling to a compact temperature under pressure. For the material. obtained by this method, the bending strength of 1000-1500 MPa. fracture toughness (Kic) - 35-40 MPa M ^ "'^ relative deformation at bending 3.0-3.5%. and its phase composition A120z-A1-51S |
