本研究探讨了纳米结构金属薄膜和功能梯度涂层的加工和表征。新的电化学处理技术为基础的梯度涂层的制造是一个主要的焦点。根据微观组织研究以及力学和腐蚀试验结果对工艺参数进行了优化。在纳米结构金属薄膜中，有两种途径：一是晶粒结构和晶界扩散在金属薄膜反应中的作用；另一项是与IBM合作，对用于薄膜存储介质的纳米结构磁性薄膜的晶界偏析进行跨学科研究。几个本科项目将被浓缩并设置为实验室实验，以供高年级本科生/研究生入门课程使用。“金属薄膜和涂层：加工、结构和性能”，这门课最近被引入了课程。纳米结构金属薄膜在微电子和信息存储技术方面不断取得重大进展。功能梯度材料作为发动机部件的热障涂层，在未来的燃气轮机发电设计中具有重要的潜力。* * *

9458000 Barmak This research examines processing and characterization of nanostructured metal films and functionally gradient coatings. New electrochemically-based processing techniques for the fabrication of gradient coatings is a major focus. Processing parameters are optimized based on microstructural studies and the results of mechanical and corrosion tests. In nanostructured metal films, there is a two-fold approach: one is the role of grain structure and grain boundary diffusion in the reaction of thin metal films; the other is an interdisciplinary investigation on grain boundary segregation in nanostructured magnetic films for thin film storage media in collaboration with IBM. Several undergraduate projects will be condensed and set up as laboratory experiments for the senior undergraduate/introductory graduate level course entitled; "Metal Films and Coatings: Processing, Structure and Properties", which was recently introduced into the curriculum. %%% Nanostructured metal films continue to bring about major advances in the microelectronics and information storage technologies. Functionally gradient materials, as thermal barrier coatings in engine components, present a significant potential for future gas turbine design for power generation. ***
