Advanced ceramics from liquid feedstock for aerospace propulsion

陶瓷是一种重要的材料，将其加工成航空涂料和部件需要专门的技术。目前新材料发现和开发的方法是浪费的，能源效率低下的，并且不能代表生产规模环境。这个高级材料工程优先领域的早期职业奖学金将证明新的陶瓷成分可以用高功率、高效率和高速三阴极等离子体源以轴向注入为主要技术从液体中加工出来。我的愿景是建立建模工具和先进的材料加工技术，使设计和制造先进的陶瓷涂层和部件具有量身定制的微观结构，具有热、电和环境阻隔性能，以满足其所需的应用。这将使陶瓷涂层具有独特的微观结构，并具有微调的热、环境和电性能，用于航空燃气轮机的热障涂层，用于这些涡轮机的陶瓷基复合材料的环境障涂层，用于电动飞机辅助发电的燃料电池和太阳能电池的电解质，用于航空电动机的介电涂层。用于航空发动机各种关键部件的耐磨、耐高温氧化和耐腐蚀涂层。为了促进广泛的工业应用，我将开发一种新的高通量工艺，减少浪费，提高基于高功率，高速等离子体的可持续性，使定制陶瓷涂层和所需纳米结构的组件以及所需孔隙结构的微观结构能够以当前技术成本的一小部分大批量生产。这将使涂料生产具有定制成分，并提供前所未有的孔径、形状、分数和分布控制，这对这些涂料的热、环境和电性能至关重要。材料发现和制造的综合方法将为航空航天工业创造具有改进性能和缩短材料加工时间的产品，符合奖学金优先领域的目标。

Ceramics are an important group of materials and their processing into aerospace coatings and components requires specialist techniques. Current methodologies for new materials discovery and development are wasteful, energy inefficient, and not representative of the production scale environment. This Early Career Fellowship in the priority area of Advanced Materials Engineering will demonstrate that new ceramic compositions can be processed from liquids with a high power, high efficiency and high velocity three cathode plasma source with axial injection as the primary technique. My vision is to establish modelling tools and advanced materials processing techniques that will enable the design and manufacture of advanced ceramic coatings and components with tailored microstructure with thermal, electrical and environmental barrier properties fine-tuned to their desired applications. This will enable unique microstructure of ceramic coatings coupled with fine-tuned thermal, environmental and electrical properties for thermal barrier coatings in the aero gas turbines, environmental barrier coatings for ceramic matrix composites in those turbines, electrolytes for fuel cells and solar cells in auxiliary power generation for electric aircraft, dielectric coatings for aero electric motors, wear and high temperature oxidation and corrosion resistant coatings for various critical components in the aero-engine. To facilitate widespread industrial uptake, I will develop a new high throughput process with reduced waste and improved sustainability based on high power, high velocity plasma, enabling the production of tailored ceramic coatings and components of the required nanostructure and microstructure of the required pore architecture in large volumes at a fraction of a cost of current techniques. This will enable the manufacture of coatings with bespoke compositions and provide unprecedented control of pore size, shape, fraction and distribution which are essential for thermal, environmental and electrical properties of these coatings. The integrated approach to materials discovery and manufacture will lead to creation of products for the aerospace industry with improved properties, performances and reduced materials processing times, in line with the aims of the fellowship priority area.
