STTR Phase I: Processing, Properties and Potentials of Precursor Derived Silicon Nitride Nanoceramics

这个小型企业技术转移第一阶段项目涉及系统研究获得高性能氮化硅/碳化硅纳米复合陶瓷的加工技术。预计聚合物前驱体热化的创新方法将允许更低的固结温度，并将比传统工艺消耗更少的能源。额外的好处有望大大提高纳米复合材料的性能。预期过程系统的好处包括更广泛的商业工程应用，因为更低的加工成本和更高的组件可靠性。如果加工成本可以降低，高温性能可以提高潜在的商业应用应该是广泛的。目前设想的应用领域有：高温燃气轮机部件、连铸喷嘴部件、切削刀具、高温焊接切削刀具、高温核聚变反应堆部件。

This Small Business Technology Transfer Phase I project involves a systematic investigation of processing techniques to obtain high performance silicon nitride/silicon carbide nanocomposites ceramics. It is expected that the innovative method of polymer precursor pyrolosis will allow lower consolidation temperatures and will consume less energy than conventional processes. Additional benefits are expected to dramaticallyincrease the performance of the nanocomposites produced. Expected process system benefits include broader commercial engineering applications due to lower processing costs and higher component reliabilities.If processing costs can be reduced and high temperature performance can be enhanced potential commercial applications should be widespread. At present, the following applications are envisioned: high temperature gas turbine components, continuous casting nozzle parts, cutting tools, high temperature welding and cutting tools, and high temperature nuclear fusion reactor parts.
