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.

与其他物体进行移动接触的组件可能会磨损。磨损是限制各种组件（例如工具，机器零件和生物医学植入物）寿命的主要故障机制。估计每年造成的磨损成本为3000亿美元。增加耐磨性是提高各种组件的耐用性和成本效益的关键。表面涂层是降低磨损和扩展组件性能的重要技术。该研究计划的长期目标是开发技术和设计方法，以在技术上重要的材料上以纳米量表进行表面涂层，以实现所需的特性（例如，高磨损耐药性和出色的生物相容性）。在这项研究建议的过程中，通过专注于开发技术来应对纳米涂料领域的重要挑战并解决某些应用的关键问题，将取得长期目标的进步。一个主要主题是合成新型的纳米复合涂料并了解其基本方面，从而在纳米结构材料领域产生新知识。另一个主要主题是发现和开发有益于加拿大人的发达涂料的创新应用。
