复相陶瓷刀具材料设计的理论框架

A Theoretical Frame for Design of Composite Ceramic Tool Materials

建立了复相陶瓷刀具材料设计的理论框架 ,该框架主要包括设计要求、系统设计、组分设计、微观结构设计、工艺设计、材料制备以及材料应用等。提出在复相陶瓷刀具材料设计的理论框架中 ,应该把工件材料视为一“独立相”,充分考虑它与刀具材料之间的化学相容性问题。实验证明该研究思路是正确的 。

The computer aided design of ceramic materials is one of the important trends in the field of the advanced ceramic materials in the 21 st century. However, the corresponding theory and technology still need to be further developed. Then, a theoretical frame for the design of the composite ceramic tool materials has been proposed and established in the present study, and practical applications and analyses are also carried out. The frame consists of several main parts such as the design requirements, systematic design, composition design, microstructural design, technological design, material fabrication and application etc..It suggests that the workpiece material must be regarded as a 'separate phase', and then the chemical compatibility between the workpiece materials and the constituents of the tool material must be considered when designing ceramic tool materials. The proposed idea has been proved to be right with lots of cutting experiments. It seems that the theoretical frame is practically important for the design of the composite ceramic tool materials.
