Tooling materials science| Резюме: | The regularities of sintering under pressure of the materials 90 mаss% SiC - 10 mаss% C system were studied. The kinetic of densification, the peculiarities of structure formation, phase composition and properties of hot pressed materials produced at a pressure of 5, 10 and 25 MPa followed by silicification has been researched. It was shown that in the obtaining materials impregnation with silicon occurs completely. It was found that SiC–10C materials consist from the grains of silicon carbide surrounded by solid solution based on silicon Si–C–Ме. It was found that after the siliconization the crack resistance increased by 35%- 40% depending on the initial porosity and the kind of a carbon |
