9414610 Komanduri A study will be made of the tribological interactions between fine polishing abrasives and the surface of advanced ceramic materials (alumina and silicon nitride). The chemical and mechanical causes of material removal will be determined in detail to the extent possible by the use of a number of in situ measurement techniques, including tribological testing inside an environmental scanning electron microscope. The results will be used to validate models developed on the basis of fracture mechanics and thermodynamics. ***

9414610 Komanduri将研究精细抛光磨料与先进陶瓷材料(氧化铝和氮化硅)表面之间的摩擦学相互作用。通过使用多种现场测量技术，包括环境扫描电子显微镜内的摩擦学测试，将尽可能详细地确定材料去除的化学和机械原因。研究结果将用于验证基于断裂力学和热力学建立的模型。***
