Microwave sintering of hardmetals and ceramics

摘要

Application of microwave radiation as heat source for sintering of powder metallurgical products is described for carbide strengthened oxide ceramics and hardmetals. Besides microwave sintering of these materials examples of microwave reaction sintering are presented. The results illustrate not only the potential of microwave sintering for a major improvement of the sintering process itself but also the prospective capability of quality improvement for traditional cemented carbides as well as the development of new hard materials, with e.g. extremely refined microstructures.
