The project "deposition of ceramic thermal barrier coatings by gas flow sputtering" is intended to study the suitability of gas flow sputtering for applications in gas turbines. Although the gas flow sputtering technique has a comparably low deposition rate, it is considerably more cost-efficient than the EB-PVD method. Coatings produced by gas flow sputtering have a microstructure similar to that of EB-PVD-coatings and should thus be superior to APS coatings with respect to their life time. Furthermore, the microstructure can be controlled within a wide range. So far, no systematic investigations of the dependence of the microstructure on the process parameters have been published. In the first project phase, the parameter influence on the process has been determined using a simplified model system. In the second project phase, the results will be transferred to a full thermal barrier coating systems and the coating structure will be optimised.

“通过气流溅射沉积陶瓷热障涂层”项目旨在研究气流溅射在燃气轮机中应用的适用性。尽管气流溅射技术的沉积速率相对较低，但它比 EB-PVD 方法更具成本效益。气流溅射产生的涂层具有与 EB-PVD 涂层相似的微观结构，因此在使用寿命方面应优于 APS 涂层。此外，微观结构可以在很宽的范围内控制。到目前为止，还没有发表关于微观结构对工艺参数的依赖性的系统研究。在项目的第一个阶段，使用简化的模型系统确定了参数对过程的影响。 在项目第二阶段，研究成果将转移到全热障涂层系统中，并对涂层结构进行优化。
