Erosion mechanisms of aerospace materials

抗固体颗粒侵蚀（SPE）对于确保各种航空发动机部件的可靠、安全和最佳性能至关重要。在这种情况下，航空航天工业寻求沉积新的和新颖的耐腐蚀涂层，并提高对材料腐蚀机制的基本理解。尽管SPE在一定程度上已经研究了100多年，但仍然存在许多与影响侵蚀的不同环境条件和材料特性的影响有关的未决问题。为了应对这些挑战，蒙特利尔理工学院（PM）的功能涂层和表面工程实验室（FCSEL）与赛峰技术和MDS涂层技术（MCT）合作，建议对航空航天材料（包括金属，复合材料和涂层）的固体颗粒侵蚀机制进行基础研究。该项目分为五个相互关联和互补的工作包（WP），即：WP 1-开发侵蚀测试和其他表征方法，WP 2-金属材料的侵蚀机制，WP 3-有机基复合材料的侵蚀机制，WP 4-侵蚀机制和新一代耐侵蚀涂层的进一步发展，最后，WP 5-技术转让。该项目的主要预期影响是延长飞机发动机部件的使用寿命并提高其性能，同时大幅降低维护和运营成本，提高效率和安全性。这些活动对未来的绿色技术和可持续发展具有重大影响，它们代表了研究和培训新一代技术专家、工程师和科学家的重要机会，从社会和可持续性的角度来看，这些技术专家、工程师和科学家非常重要。因此，它将有助于蒙特利尔地区、魁北克和加拿大航空航天部门的经济和技术发展。

Resistance to solid particle erosion (SPE) is critical to ensure the reliable, safe, and optimal performance of various aircraft engine components. In this context, the aerospace industry searches for the deposition of new and novel erosion-resistant coatings and the improved fundamental understanding of materials' erosion mechanisms. Even if SPE has been studied to some degree for over 100 years, there remain numerous open questions related to the effect of different environmental conditions and material properties that affect erosion. In response to these challenges, the Functional Coating and Surface Engineering Laboratory (FCSEL) at Polytechnique Montreal (PM), in collaboration with Safran Tech and MDS Coating Technologies (MCT), proposes to perform a fundamental study of the solid particle erosion mechanisms of aerospace materials including metals, composites, and coatings. The project is divided into five interrelated and complementary work packages (WP), namely: WP1 - Development of the erosion testing and other characterization methodologies, WP2 - Erosion mechanisms of metallic materials, WP3 - Erosion mechanisms of organic matrix composites, WP4 - Erosion mechanisms and further developments of a new generation of erosion-resistant coatings, and finally, WP5 - Technology transfer. The main anticipated impact of this project is extending the life and improving the performance of aircraft engine components while enabling an important reduction in maintenance and operation costs and enhancing efficiency and safety. These activities have a strong influence on future green technologies and sustainable development, and they represent an important opportunity for research and for training a new generation of technologists, engineers, and scientists highly important from societal and sustainability points of view. As such, it will contribute to the economic and technological development of the aerospace sector in the Montreal area, in Quebec, and Canada.
