Utilization null of the TBC canning thickness measurement equipment and this manner and the TBC canning thickness measurement equipment in order to execute manner and this manner which detect at least the thickness of TBC canning of 1 aerofoils of the fluid machinery

摘要

This invention, the fluid machinery (1) at least 1 wings (4 and 11) TBC coating (12) regards the method of detecting thickness. In that case, one electromagnetic wave, 1 wings (4 and 11) is transmitted by the surface at least at least, that one electromagnetic wave is reflected 1 wings (4 and 11) with at least at least at least partly, the reflected part of one electromagnetic wave is received at least, reprocesses. Furthermore, at least one electromagnetic wave, it is transmitted at the frequency which it can be brought together to the thickness of TBC coating, in that case, one transmission electromagnetic wave causes phase change at least when reflecting, phase of that at least one transmission electromagnetic wave, thickness of TBC coating is detected with phase of one reception electromagnetic wave by comparison, by the phase comparison at least. In addition this invention, regards the utilization of the TBC coating thickness measurement equipment, and this method and the TBC coating thickness measurement equipment in order to execute this method.
