Research on the Engineering Performance of Ceramic Die Materials

The engineering performances of the ceramic materials such as cermet, ZTA, TZP, TZP/Al2O3, TZP/TiC/Al2O3, Al2O3/TiC, PSZ, Si3N4 and Sialon, etc. have been investigated and analyzed in the present study when they were used as die materials in various operations such as drawing, extrusion, punching and stamping, shearing and isothermal forging, etc. Problems in the research and application of ceramic die materials are discussed, and the perspectives in the application of ceramic die materials are given. It is proposed that toughening and strengthening of the ceramic die materials, optimum design of die structures and surface treatment techniques with ceramic powders for die materials, etc. are the possible and effective methods to improve the engineering performances of ceramic die materials. With the rapid development of die technology, ceramic die materials will have increasingly wider perspectives of application in the future.
