I have established a strong and coordinated research program in the area of Nanoengineered Surface Coatings to address the key issues in surface science and engineering since 2005. The long term goal of the research program is to develop technologies and design methods to engineer the surfaces of technologically important materials at the nanometer scale to achieve desired properties for targeted mechanical, electrical, optical, and biomedical applications.     Over the past six years, my research team has been focusing on the development of plasma and ion beam based technologies and design methods to address key issues in the synthesis and characterize novel nanostructured thin films/coatings for industrial and biomedical applications and attempted to developed novel nanocomposite superhard coatings. Significant progress has been made towards the long term research goal. These include (1) the synthesis and characterization of diamond based coatings on biomedical grade CoCrMo alloys, Ti alloys, stainless steels, and other technical important alloys by interfacial design and process development, (2) the fabrication of high quality vanadium and niobium oxide films for optical and electrical applications, and the synthesis of novel Cr-Zr-O nanocomposite coating with superhardness for advanced cutting tools, and (3) the synthesis of Ta coatings with a new crystalline structure. In the present renewal application, I propose to work on long term research goal by developing technologies to address important challenges in nanostructured coatings and solve their critical problems for mechanical, biomedical, and electronic applications. Specifically, the proposed research will have the following short-term objectives over the next 5 years.     1. Developing adherent hard coatings on joint implant alloys with improved properties and performance for longer service lifetime.     2. Developing VO2-based films for simultaneous data processing and data storage.     3. Understanding the fine structure and clarifying the formation mechanism of the novel superhard Cr-Zr-O coating we have recently developed in order to engineering the coating for cutting tools to improve their efficiency and performance.     This research focuses on the creation, characterization, and application of novel nanostructured coatings for advanced data processing and data storage, cutting tools, and biomedical implants with a menu of targeted desirable qualities. It will lead to a better understanding of the basic scientific issues related to nanomaterials and their interactions with other materials and human tissues. It will contribute significantly to enhancing the capacity for nanomaterials synthesis and application in Canada. Finally, the research will provide excellent opportunities for training highly qualified personnel with integrated knowledge in materials science and engineering, mechanical and biomedical engineering, physics, chemistry, electronics, and data analysis.

自2005年以来，我在纳米工程表面涂层领域建立了一个强大而协调的研究计划，以解决表面科学和工程中的关键问题。该研究计划的长期目标是开发技术和设计方法，以在纳米级设计具有重要技术意义的材料的表面，以获得目标机械、电气、光学和生物医学应用所需的特性。在过去的六年里，我的研究团队一直专注于基于等离子体和离子束的技术和设计方法的开发，以解决工业和生物医学应用中合成和表征新型纳米结构薄膜/涂层中的关键问题，并试图开发新型纳米复合超硬涂层。在实现长期研究目标方面取得了重大进展。包括(1)通过界面设计和工艺开发在生物医用级CoCrMo合金、钛合金、不锈钢和其他重要技术合金上合成和表征金刚石基涂层；(2)制备高质量的光学和电学用钒和铌氧化物薄膜；(3)合成用于先进刀具的新型具有超硬性能的铬-锆-氧纳米复合涂层；(3)合成具有新晶体结构的钽涂层。在目前的更新应用中，我建议通过开发技术来解决纳米结构涂层中的重要挑战，并解决其在机械、生物医学和电子应用中的关键问题，从而实现长期的研究目标。具体地说，拟议的研究在未来5年将有以下短期目标。在关节植入合金上开发具有更高性能和性能的附着力硬质涂层，以延长使用寿命。开发同时用于数据处理和数据存储的VO2基薄膜。了解新型超硬铬锆氧涂层的精细结构，阐明其形成机理，为刀具涂层的工程化设计，提高刀具的效率和性能。此外，这项研究的重点是新型纳米结构涂层的创建、表征和应用，用于先进的数据处理和数据存储、刀具和生物医学植入物，并具有一系列有针对性的理想质量。它将使人们更好地了解与纳米材料及其与其他材料和人体组织的相互作用有关的基本科学问题。这将大大提高加拿大纳米材料合成和应用的能力。最后，这项研究将为培养具有材料科学与工程、机械与生物医学工程、物理、化学、电子学和数据分析等综合知识的高素质人才提供极好的机会。
