摘要:

Silicon nitride (Si3N4) ceramics exhibit a very unique microstructure, which contains whisker-like elongated grains embedded in a fine-grained matrix.  The class of Si3N4 ceramics generally exhibits very good mechanical properties combined with good resistance to wear, corrosion, and oxidation.  Therefore, Si3N4 ceramics were designed and implemented as hot-section structural components such as vane, blade, and turbo rotor in gas turbine and microturbine engines under several ceramic turbine programs funded by governments in 1990.  The integrated global research efforts executed allow the ceramic community to gain a much better insight into how to design such a microstructure and the chemistry of interfaces as they closely relate to mechanisms for enhanced toughness in self-reinforced ceramics.  It is also now well known that the oxide additives employed could influence the alpha-to-beta Si3N4 phase transformation, microstructural evolution, microstructural and chemical bonding of interfacial thin film during the processing and sintering procedures.  Recently, much of attentions on Si3N4 ceramic have now focused on its application as an insulator substrate for power electronic components; i.e., IGBT, due to its excellent performance in mechanical properties and reliability to overcome the increased thermal stress and mechanical vibration generated during application conditions. This presentation will focus on engineering design and processing of chemical compositions and also microstructure of Si3N4 ceramics to achieve a combined physical and mechanical property targeted for a specific industrial application. The implications and challenges to achieve the aimed properties and performances learned through the course of these studies would also be presented and discussed in the paper.
