航空发动机、压气机和涡轮都采用可磨损密封，以降低燃油消耗。它们的作用是将发动机转子的旋转叶片和机壳之间的间隙降至最低，以减少空气泄漏(压缩机)或空气燃料燃烧产物泄漏(涡轮机)。涡轮机的运行温度(高达1800°C)会引起叶片的热膨胀，并引起接触，从而损坏叶片或机壳。因此，在接触的情况下，刀片应在不损坏的情况下移除适用于机壳的可磨损密封件。此外，密封必须耐受涡轮环境。已观察到等离子喷涂操作参数与耐磨涂层性能之间的直接关系。本研究的目的是确定YSZ-聚酯耐磨复合涂层的这些关系。这项研究是在7FP欧洲项目E-BREAK的框架内进行的，以实现欧洲航空研究和创新咨询委员会的环境目标。
Abradable seals are used in aircraft engine compressor and turbine to decrease fuel consumption. Their role is to minimize the clearance between the rotating blades of an engine rotor and the casing to reduce air leakages (compressor) or air-fuel combustion product leakages (turbine). Operating temperatures in turbines (up to 1800 °C) can induce a thermal expansion of the blades and give rise to contacts providing damages to the blades or casing. Thus, in case of contact, the blade should remove the abradable seals applied to the casing without being damaged. Besides, the seal must be resistant to the turbine environment. Direct relationships have been observed between plasma spray operating parameters and abradable coating performances. The aim of this study is to determine those relationships for YSZ-Polyester abradable composite coatings. This study is conducted within the framework of the 7FP European project E-BREAK to reach the environmental objectives of the European Advisory Council for Aviation Research and innovation.
