U.S.-Korea Cooperative Research: Alteration of the Effects of Sintering Additives on the Oxidation & Tribological Behavior of Silicon Nitride

杜9710142 该奖项支持Stevens Institute of Technology的Honghua Du博士和韩国Sun Moon University的Soo Lee博士之间为期两年的合作研究项目，即“改变烧结添加剂对氮化硅氧化和摩擦学行为的影响”。“这项研究将研究铝离子注入和添加氧化铝到氮化硅产品与氧化镁烧结的影响。 实验与表面和晶界的化学特性，应导致更好地了解它们的关系，氧化和磨损性能，并在氮化硅陶瓷系统中的表面或界面反应，扩散和摩擦化学相互作用等基本现象。 该项目将联合收割机韩国团队在陶瓷加工和烧结方面的专业知识与杜博士在这些材料的耐腐蚀性方面的广泛工作相结合。 氮化硅陶瓷广泛用于先进发动机和其他结构应用。 因此，这些陶瓷的氧化和磨损提出了重要的工程问题。 ***

Du 9710142 This award supports a two-year collaborative research project between Dr. Honghua Du of the Stevens Institute of Technology and Dr. Soo Lee of Sun Moon University in Korea on "Alteration of the Effects of Sintering Additives on the Oxidation and Tribological Behavior of Silicon Nitride." The study will investigate the effects of aluminum ion implantation and the addition of alumina to silicon nitride products sintered with magnesia. Experimentation with surface and grain boundary chemical characteristics should lead to a better understanding of their relationship to oxidation and wear properties and to such basic phenomena as surface or interface reactions, diffusion, and tribochemical interactions in the silicon nitride ceramic system. This project will combine the expertise of the Korean team in the processing and sintering of ceramics with Dr. Du's extensive work on the corrosion resistance of these materials. Silicon nitride ceramics are used extensively in advanced engines and for other structural applications. Thus, the oxidation and wear of these ceramics presents important engineering issues. ***
