NON-TECHNICAL DESCRIPTION: Significant cost savings can be achieved by optimizing the maintenance and servicing of machinery that is used in high temperature harsh industrial environments, such as those found in turbine engines, petrochemical processing plants, combustion burners, power plant boilers, oil/gas drilling, metals smelting and refining, and ceramic manufacturing. Unfortunately, currently available thin film materials rapidly degrade in the high temperature harsh conditions of interest to the high temperature industry sector, making sensors and other monitoring devices unstable and short-lived. This project focuses on developing a new class of ceramic-based thin film materials that are stable in these extreme high temperature harsh environments. The development of these high temperature components will improve sustainability by enabling the deployment of miniaturized sensors, actuators, and other electronic components that can be used to reduce overall energy usage and increase the longevity of complex, expensive high temperature machinery. TECHNICAL DETAILS: Investigations are being carried out on nanocomposite multilayer thin film structures consisting of oxides, borides, or silicides integrated with Pt-based materials on sapphire, langasite, and Inconel substrates. Rapid materials screening experiments are used to determine the most stable nanocomposite architectures consisting of diffusion barriers, adhesion layers, conducting electrodes, and capping passivation layers. Experiments on the most promising nanocomposite systems focus on probing materials processes such as surface reactivity, interdiffusion, phase formation, oxidation, recrystallization, agglomeration, and roughening. Prototype sensor devices comprised of the ceramic-based nanocomposite films are being evaluated within controlled environment furnaces and small scale turbine engines. The project is educating and training three graduate students and four undergraduates in the areas of ceramic film synthesis, high temperature materials, and characterization of sensor devices. The students are also learning about materials sustainability strategies and technology transfer to the sensor community.

非技术描述：通过优化在高温恶劣工业环境中使用的机械的维护和保养，可以实现显著的成本节约，例如在涡轮机发动机、石化加工厂、燃烧器、发电厂锅炉、石油/天然气钻探、金属冶炼和精炼以及陶瓷制造中使用的机械。不幸的是，目前可用的薄膜材料在高温工业部门感兴趣的高温苛刻条件下迅速降解，使得传感器和其他监测设备不稳定且寿命短。 该项目的重点是开发一类新的陶瓷基薄膜材料，这些材料在这些极端高温恶劣的环境中稳定。这些高温部件的开发将通过部署小型化传感器、致动器和其他电子部件来提高可持续性，这些电子部件可用于减少整体能源使用并延长复杂、昂贵的高温机械的寿命。 技术规格：正在进行调查的纳米复合材料的多层薄膜结构组成的氧化物，硼化物，或硅化物集成与铂基材料的蓝宝石，硅酸镧镓和铬镍铁合金基板。快速材料筛选实验用于确定最稳定的纳米复合材料的结构组成的扩散屏障，粘附层，导电电极，和盖帽钝化层。最有前途的纳米复合材料系统的实验重点是探测材料过程，例如表面反应性、相互扩散、相形成、氧化、重结晶、团聚和粗糙化。由陶瓷基纳米复合薄膜组成的原型传感器装置正在受控环境熔炉和小型涡轮机发动机中进行评估。该项目在陶瓷薄膜合成、高温材料和传感器器件表征领域教育和培训三名研究生和四名本科生。 学生们还学习了材料可持续性战略和传感器社区的技术转移。
