This research programs will develop new, innovative surface engineering solutions for aerospace, including protective and solid-lubricating coatings fabricated by cold spray and physical vapor deposition. Surface engineering research is important for aerospace and many other industries to protect expensive infrastructure, increase reliability and reduce energy losses and fuel consumption. In the next 5 years, the principal investigator, with more than 20 years of experience on surface engineering, will train 1 research associate and 11 students (5 doctoral, 1 masters and 5 undergraduate) that will develop new coatings and test their mechanical and tribological properties. It is expected that at least six new coating technologies will be developed and tested for their process-structure-property relationships. Findings will be disseminated at international conferences and in scholarly publications. A specific focus will be the design of a hybrid coating structure for long term reliability of components used on space vehicles and lunar/Martian rovers for future space exploration missions. Development of the coatings and testing will be broken down in 4 main sub-projects: composite coatings by cold spray, solid lubricant coatings by PVD, hybrid coatings using both technologies and finally testing of these coatings in space simulators. This research will aid significantly Canada's part in future space missions. The coatings designed will also have applications in commercial aerospace and other industries (energy, hydropower, mining, etc.). The surface engineering research will continue to foster green and sustainable manufacturing initiatives in Canada and the trained HQP will be well positioned to continue this effort in Canadian industry. The research conducted will be a significant contribution to the fields of surface engineering and tribology. New understanding of the cold spray coating process to make composite coatings will be gained and the viability and benefits of duplex coatings will be determined, pushing forward a newer area of surface engineering that has potential to create high performance and adaptive coatings for the most demanding applications.

这项研究计划将为航空航天开发新的、创新的表面工程解决方案，包括通过冷喷涂和物理气相沉积制造的防护和固体润滑涂层。表面工程研究对航空航天和许多其他行业保护昂贵的基础设施、提高可靠性、减少能源损失和燃料消耗具有重要意义。在接下来的5年里，这位拥有20多年表面工程经验的首席研究员将培训1名副研究员和11名学生(5名博士、1名硕士和5名本科生)，他们将开发新的涂层并测试其机械和摩擦学性能。预计将开发至少六种新的涂层技术，并对其工艺-结构-性能关系进行测试。研究结果将在国际会议和学术出版物上传播。一个特别的重点将是设计一种混合涂层结构，以确保用于未来空间探索任务的航天器和月球/火星漫游车上的部件的长期可靠性。涂层的开发和测试将分为4个主要的子项目：冷喷涂复合涂层、PVD固体润滑剂涂层、使用这两种技术的混合涂层以及最终在空间模拟器中测试这些涂层。这项研究将极大地帮助加拿大参与未来的太空任务。所设计的涂料还将应用于商业航空和其他行业(能源、水电、采矿等)。表面工程研究将继续在加拿大促进绿色和可持续制造倡议，训练有素的HQP将处于有利地位，在加拿大工业中继续这一努力。这项研究将对表面工程和摩擦学领域做出重大贡献。我们将对冷喷涂复合涂层的工艺有了新的了解，并将确定双层涂层的可行性和效益，从而推动表面工程的一个新领域，有可能为最苛刻的应用创造高性能和适应性的涂层。
