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. ***

该奖项支持由史蒂文斯理工学院的杜宏华博士和韩国sunmoon大学的Soo Lee博士进行的为期两年的合作研究项目“烧结添加剂对氮化硅氧化和摩擦学行为的影响的改变”。本研究将探讨铝离子注入和添加氧化铝对镁烧结氮化硅产品的影响。对表面和晶界化学特性的实验应该能更好地理解它们与氧化和磨损性能的关系，以及氮化硅陶瓷系统中表面或界面反应、扩散和摩擦化学相互作用等基本现象。该项目将结合韩国团队在陶瓷加工和烧结方面的专业知识，以及杜博士在这些材料的耐腐蚀性方面的广泛工作。氮化硅陶瓷广泛用于先进的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。＊＊＊
