项目摘要
A compressor blade must have a clearance gap between its tip and the engine casing to avoid the blade from seizing and damage. This gap is typically sealed with an abradable (soft) coating to prevent air flowing back over the blade tip during service. To allow safe operation at elevated temperatures typically found in high-pressure compressor stages (up to 500°C), abradable coating matrices are manufactured using secondary phases such as solid lubricants, to minimize the coating's material transfer and promote abradability. AlSi-hBN is a potential metal matrix-solid lubricant coating material successfully manufactured by means of plasma spraying [ref]. However, its abradability is currently limited, mainly due to the inability of the plasma spray process to retain a sufficient amount of hBN in the coating. The proposed project aims at determining if the pulsed gas dynamic spray process (PGDS) can be adapted and developed to produce Al-Si+hBN coatings with properties (microstructure, hardness, adhesion, abradability) meeting the industrial collaborator specifications. Fundamental research is required to increase the understanding of the PGDS application method mechanisms and its ability to improve AlSi+hBN coatings durability.
压气机叶片的叶尖和发动机壳体之间必须有间隙,以避免叶片卡住和损坏。该间隙通常用可磨损(软)涂层密封,以防止在服务期间空气在叶片尖端上回流。为了允许在高压压缩机级中通常存在的高温(高达500°C)下安全操作,可磨损涂层基质使用第二相(诸如固体润滑剂)来制造,以最小化涂层的材料转移并提高耐磨性。AlSi-hBN是通过等离子喷涂成功制造的潜在金属基质固体润滑涂层材料[参考文献]。然而,其耐磨性目前是有限的,主要是由于等离子喷涂工艺不能在涂层中保留足够量的hBN。该项目旨在确定脉冲气体动力喷涂工艺(PGDS)是否可以适应和发展,以生产性能(微观结构,硬度,附着力,耐磨性)符合工业合作者规范的Al-Si+hBN涂层。需要进行基础研究,以增加对PGDS应用方法机制及其改善AlSi+hBN涂层耐久性的能力的理解。
