Description

technical field [0001] The invention belongs to the technical field of detection of thermal barrier coatings, and in particular relates to a method and equipment for measuring and calculating the life of thermal barrier coatings. Background technique [0002] In the service environment, the hot end components of industrial gas turbines are not only subjected to high temperature and high pressure gas, but also to high heat flow input, high temperature gradient, stress gradient, centrifugal force and other effects. Thermal barrier coating (thermal barrier coating, TBC) can effectively prolong the service life of the hot end components. Therefore, predicting the failure time of TBC can effectively realize the prediction of the service life of the hot end components of the gas turbine. [0003] The common composition of the TBC system is the outermost ceramic layer (TC), the bonding layer (BC), and the thermally grown oxide layer (thermally grown oxide, TGO) that grows over tim...
