Abstract
A type of testing equipment for detecting the failure process of thermal barrier coating in a simulated working environment; it belongs to the field of simulated special working environment equipment. Testing equipment includes testing platform equipped with static or dynamic specimen holding apparatus, simulated module of working environment, real-time detection module, control panel. This invention is capable of simulating a high temperature, erosive, corrosive working environment for thermal barrier coated turbine blade of aero-engines; simulate high speed spinning working environment for thermal coated blade, simulate static working environment for guiding blade; perform real-time testing of temperature field, 3-D displacement field, crack initiation and expansion, surface oxidation, etc. This invention has achieved complete integration of high temperature, erosive, corrosive working environment for thermal barrier coating and complete integration static or dynamic working environment, complete integration of simulated working environment and real-time testing, thus providing a crucial testing platform and reference data to properly understand the failure mechanism of thermal b…
