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.

该研究计划将开发用于航空航天的新的，创新的地表工程解决方案，包括由冷喷雾剂和物理蒸气沉积制造的保护性和固体润滑涂料。表面工程研究对于航空航天和许多其他行业来说很重要，可以保护昂贵的基础设施，提高可靠性并减少能源损失和燃油消耗。在接下来的5年中，拥有20多年的地表工程经验的首席研究员将培训1名研究助理和11名学生（5名博士学位，1名硕士和5个本科生），这些研究员将开发新的涂料并测试其机械和摩擦学特性。预计将至少开发和测试六种新的涂层技术，以实现其过程结构 - 培训关系。调查结果将在国际会议和学术出版物中传播。特定的重点是设计混合涂料结构，用于用于太空车辆和月球/火星漫游车的长期可靠性，用于未来的太空探索任务。涂料和测试的开发将在4个主要的子项目中分解：冷喷雾剂的复合涂料，通过PVD进行的实心润滑剂涂料，使用这两种技术的混合涂料，最后在太空模拟器中测试了这些涂层。这项研究将有助于加拿大在未来的太空任务中的作用。设计的涂料还将在商业航空航天和其他行业（能源，水电，采矿等）中应用。地表工程研究将继续在加拿大促进绿色和可持续的制造计划，而受过训练的HQP将在加拿大行业继续努力。进行的研究将是对地表工程和摩擦学领域的重要贡献。将获得对制作复合涂料的冷喷涂过程的新了解，并将确定双链涂层的生存能力和好处，从而推动更新的地表工程领域，该领域有可能为最苛刻的应用创建高性能和自适应涂料。
