Synthesis, characterization, and application of nanostructured hard coatings

与其他物体运动接触的部件会受到磨损。磨损是限制工具、机器部件和生物医学植入物等各种组件寿命的主要失效机制。全球每年因磨损造成的损失估计为3000亿美元。提高耐磨性是提高各种部件的耐用性和成本效益的关键。表面涂层是降低磨损、提高零件性能的重要技术。该研究计划的长期目标是开发技术和设计方法，在技术重要的材料上设计纳米级的表面涂层，以实现各种应用所需的性能（例如高耐磨性和优异的生物相容性）。在这项研究计划的过程中，将通过专注于开发技术来应对纳米涂层领域的重要挑战并解决某些应用的关键问题，从而朝着长期目标取得进展。一个主要的主题是合成新的纳米复合材料涂层，并了解其基本方面，从而产生在纳米结构材料领域的新知识。另一个主题是发现和开发有利于加拿大人的涂层的创新应用。

Components in moving contact with other bodies are subject to wear. Wear is the major failure mechanism limiting the lifetime of various components such as tools, machine parts, and biomedical implants. The world-wide cost due to wear is estimated to be $300 billion per year. Increasing wear resistance is the key to improving the durability and cost effectiveness of various components. Surface coating is an important technology for reducing wear and extending performance of components. The long-term goal of the research program is to develop technologies and design methods to engineer surface coatings at the nanometer scale on technologically important materials to achieve desired properties (e.g. high wear resistance and excellent biocompatibility) for various applications. During the course of this research proposal, progress will made towards long-term goal by focusing on developing technologies to address important challenges in the area of nanocoatings and solve critical problems for some applications. One major theme is to synthesize novel nanocomposite coatings and understand their basic aspects, thus generating new knowledge in the area of nanostructured materials. Another main theme is to discover and develop innovative applications of the developed coatings that benefit Canadians.
