项目摘要

This NSF-Europe award to University of Illinois Urbana-Champaign is to carry out synthesis and characterization of nanostructured diborides of Zirconium, Titanium and Chromium for super-hard coatings with low friction coefficients and low wear rates. This collaborative research with Centre d'Etudes Chimie-Metallurgie, CNRS, Vitry Cedex, France will be in the following areas: (1) novel synthesis techniques for nanophase transition metal diboride, in particular by chemical vapor deposition of mixed phase materials; (2) characterization of structure and defects in amorphous and nanocrystalline films through the advanced TEM techniques of fluctuation electron microscopy and the geometric phase image method; and (3) analysis of the friction and wear behavior in terms of driven systems as a theoretical framework. Synthesis and characterization of biborides carried out by this study are likely to produce an improved understanding of how microstructure varies with stoichiometry of diborides with transition metals, CVD conditions used to prepare them, and wear parameters such as sliding speed and contact load.Development of energy efficient tools and devices with hard coatings for wear resistance and low friction will have significant technological and societal benefit. This collaboration with the French scientists will take advantage of the complementary knowledge and experience between the two teams. Training and teaching of graduate and undergraduate students, and outreach programs including recruitment of women and under-represented groups using existing programs at the University campus are parts of this award.
这项授予伊利诺伊大学厄巴纳-香槟分校的NSF-欧洲奖是为了合成和表征用于低摩擦系数和低磨损率的超硬涂层的纳米结构二硼化锆、钛和铬。这项研究将与法国国家研究中心的Chimie-Metallurgie中心合作开展以下领域的研究:(1)纳米相过渡金属二硼化物的新型合成技术,特别是通过混合相材料的化学气相沉积;(2)通过先进的电子显微镜技术和几何相位图像方法表征非晶和纳米晶薄膜的结构和缺陷;以及(3)以驱动系统为理论框架分析摩擦磨损行为。本研究所进行的硼化物的合成和表征可能有助于更好地了解含过渡金属的硼化物的化学计量比、制备它们的CVD条件以及滑动速度和接触载荷等磨损参数对其微观结构的影响。开发具有耐磨性和低摩擦的硬质涂层的节能工具和设备将具有显著的技术和社会效益。这次与法国科学家的合作将利用两个团队之间互补的知识和经验。对研究生和本科生的培训和教学,以及包括利用大学校园现有方案招募妇女和代表性不足群体的外联方案,都是该奖项的一部分。
