US-France Cooperative Research: Tribological Thin Films on Rough Surfaces: Design, Analysis, Characterization, Fatigue and Wear

这项为期三年的美法机械工程合作奖涉及纽约州立大学布法罗分校和法国里尔科技大学的研究人员和学生。美国的Andres Soom和Gary F. Dargush以及法国的Jacky Lesage和Gerard Mesmacque将领导这个合作项目，模拟薄涂层和薄膜的摩擦学性能和失效。特别是，他们将进行一系列实验，得出磨损或薄膜失效的模式。同时，三维接触应力和应变的计算力学建模也将得到发展。美国研究人员是计算、接触力学和摩擦学测试方面的专家。这是法国在表征、制备和薄膜失效以及纳米压痕测量方面的能力的补充。薄膜和涂层经常用于提高机械部件和生产工具的性能和耐用性，因为在与表面接触时会发生一些滑动。最近先进的表面设计挑战了当前基于机械性能设计薄膜和预测行为的能力。这种共同努力将促进对生命周期性能和预测建模的理解。该奖项代表了美国方面向美国国家科学基金会和法国国家科学研究中心（CNRS）联合提出的建议。美国国家科学基金会将支付美国研究人员和研究生的旅费和生活费。CNRS将支持法国研究人员和研究生访问美国。

0233313SoomThis three-year award for US-France collaboration in mechanical engineering involves researchers and students at the State University of New York at Buffalo and the University for Science and Technology in Lille, France. Andres Soom and Gary F. Dargush in the US and Jacky Lesage and Gerard Mesmacque in France will lead this collaborative program to model the tribological performance and failure of thin coatings and films. In particular, they will conduct a series of experiments, resulting in patterns of wear or film failure. In parallel, computational mechanical modeling of 3D contact stresses and strains will be developed. The US investigators are expert in computational, contact mechanics and tribological testing. This is complemented by French capabilities in characterization, preparation and failure of thin films, and nano-indentation measurements. Thin films and coatings are frequently used to enhance performance and durability of mechanical components and production tooling where some sliding occurs at contact with the surface. Recently advanced designs of surfaces have challenged current ability to design films, and predict behavior, based on mechanical properties. This joint effort will advance understanding of life-cycle performance and predictive modeling. This award represents the US side of joint proposals to the NSF and the French National Center for Scientific Research (CNRS). NSF will cover travel funds and living expenses for the US investigators and graduate student. CNRS will support the visits of the French researchers and graduate students to the United States.
