The productivity, product quality, and environmental sustainability of Canada's manufacturing sectors are closely linked to their ability to remain at the forefront of new material development and the use of efficient manufacturing processes. Tool wear, built up edge formation, and adhesion are among the factors that influence a manufacturing process's efficiency and surface quality of the machined or formed part. It is also important to control of a material's microstructure at each stage in the manufacturing process as it is often the microstructure of the near surface region that dictates the product's manufacturability performance. The proposed program aims at developing new tribological methods that will increase efficiency of manufacturing processes, particularly machining and forming of engineering components made of lightweight alloys. The material systems that will be studied will consist of Al and Mg alloys that are of critical importance for fuel economy conscious transportation sectors. The microstructural aspects of surface and interface damage mechanisms will be examined by undertaking experimental and computational studies. The research will consist of two related programs: A 'Tribology of Sheet Metal Forming' program that will delineate coefficients of friction and contact damage mechanisms between Al, and Mg alloy sheets and die surfaces in order to increase their formability and surface quality. A Tribology of Machining' program that will focus on improving the efficiency of cutting and drilling operations of light metal castings typically hindered by material adhesion. Each of these two programs has unique research requirements, yet the fundamental issues are similar and can be addressed using a common research methodology that will include: i) the development of new testing methods to simulate interfacial tribo-chemical failure mechanisms that occur during manufacturing conditions; ii) the delineation of wear, adhesion and friction mechanisms from microstructural and atomistic points of view; iii) the design of interfaces-- using new coatings, solid lubricants, textured surfaces-- to increase formability of lightweight sheet metals and effectiveness of machining processes using the results of experimental and computational work. In summary, the research program will generate fundamental scientific and engineering knowledge to produce new energy efficient manufacturing technologies and improve quality of lightweight components. The research proposal is structured to provide the highest possible output of HQP who will utilize the new technology and enhance Canada's ability to compete in the global economy.

加拿大制造业的生产力、产品质量和环境可持续性与其保持新材料开发和使用高效制造工艺的能力密切相关。刀具磨损、累积刃口形成和粘附是影响加工或成形零件的制造工艺效率和表面质量的因素之一。在制造过程的每个阶段控制材料的微观结构也很重要，因为通常是近表面区域的微观结构决定了产品的可制造性性能。 该计划旨在开发新的摩擦学方法，以提高制造工艺的效率，特别是由轻质合金制成的工程部件的加工和成型。 将被研究的材料系统将包括铝和镁合金，这是至关重要的燃油经济性意识的运输部门。表面和界面损伤机制的微观结构方面将进行实验和计算研究。该研究将包括两个相关的项目： 一个“金属板成形摩擦学”程序，将描绘铝和镁合金板和模具表面之间的摩擦系数和接触损伤机制，以提高其可成形性和表面质量。 一个机械加工的摩擦学的程序，将重点放在提高效率的切割和钻孔操作的轻金属铸件通常阻碍材料的粘附。 这两个项目都有独特的研究要求，但基本问题是相似的，可以使用共同的研究方法来解决，包括： i）开发新的测试方法，以模拟在制造条件下发生的界面摩擦化学失效机制; ii）从微观结构和原子观点描述磨损、粘附和摩擦机制; iii）界面设计--使用新的涂层、固体润滑剂、纹理表面--以提高轻质金属板的可成形性和使用实验和计算工作结果的加工过程的有效性。 总之，该研究计划将产生基础科学和工程知识，以产生新的节能制造技术，并提高轻质部件的质量。该研究提案的结构是提供HQP谁将利用新技术和提高加拿大的能力，在全球经济中的竞争可能的最高输出。
