| Abstract: | The physical and chemical compatibility is one of the important aspects in the design of the composite ceramic tool materials. Based on the theory of the thermal dynamics, a model for the calculation of the chemical compatibility of the ceramic tool materials has been established in this paper. Then, the chemical compatibilities of the possible composition systems of the composite ceramic tool materials are computed and analyzed by means of the computer programming. After that, the physical compatibility of the ceramic tool materials is discussed generally. Results show that the optimum matching of the coefficient of the thermal expansion and the Young's modulus of the constituents is noticeably necessary for the achievements of both the high flexural strength and the fracture toughness of the composite ceramic tool materials. |
