Tribology of thermal sprayed nanocomposite coatings for ultra-low-wear in aero-engines

本项目的目的是通过液体原料悬浮液和溶液前体(SSP)热喷涂将增强材料(例如石墨烯)加入陶瓷和金属陶瓷(陶瓷+金属)基体中，开发热喷涂纳米复合涂层。航空发动机各种旋转、滑动和振动部件的磨损是一个需要频繁检修的重大问题，这浪费了宝贵的时间和资源。航空发动机在最恶劣的条件下运行，在极端温差下频繁地进行热循环和机械循环。目前航空发动机中的涂层使用寿命较短，因此有必要确定和开发下一代超低磨损涂层的材料和工艺。

The aim of this project is to develop thermally sprayed nanocomposite coatings through incorporating reinforcement materials (e.g., graphene) into ceramic and cermet (ceramic + metallic) matrices via liquid feedstock based Suspension and Solution Precursor (SSP) thermal spray. Wear of various rotating, sliding and vibrating parts in aero engines is a major issue that requires frequent overhauls which wastes valuable time and resources. Aero engines operate at the harshest conditions with frequent thermal and mechanical cycling in extreme temperature differentials. Current coatings in the aero engines have a shorter lifetime and hence, there is a research need to identify and develop the materials and processes for the next generation of ultra-low-wear coatings.
