Method for determining the layer thickness of a TBC coating of at least one blade of a non-positive-displacement machine, a corresponding TBC layer thickness measuring device for carrying out the method and use of the method and the TBC layer thickness measuring device
Abstract:
A method determines the layer thickness of a TBC coating of at least one blade of a non-positive-displacement machine. To this end, at least one electromagnetic wave is emitted to the surface of the at least one blade, the at least one electromagnetic wave is then at least partially reflected by the at least one blade, and the reflected portion of the at least one electromagnetic wave is received and subsequently processed. In addition, the at least one electromagnetic wave is emitted with a frequency matched to the layer thickness of the TBC coating, and the phase of the at least one electromagnetic wave is compared with the phase of the at least one received electromagnetic wave. The at least one emitted electromagnetic wave undergoes a phase change during reflection and the layer thickness of the TBC coating is determined by the phase comparison.
Abstract(Chinese):

一种方法确定非正排量机器的至少一个叶片的TBC涂层的层厚度。 为此，至少一个电磁波被发射到至少一个叶片的表面，然后至少一个电磁波被至少一个叶片至少部分地反射，并且至少一个电磁波的反射部分 波被接收并随后处理。 此外，以与TBC涂层的层厚度相匹配的频率发射至少一个电磁波，并且将至少一个电磁波的相位与至少一个接收的电磁波的相位进行比较。 至少一个发射的电磁波在反射期间经历相变，并且通过相位比较来确定TBC涂层的层厚度。
