Abstract

The invention discloses a turbine blade thermal barrier coating working condition simulation experiment test system. The system comprises working state simulation equipment, service environment simulation equipment and detection equipment; the working state simulation equipment is arranged at one side of a to-be-tested turbine blade thermal barrier coating, connected with the to-be-tested turbineblade thermal barrier coating and used for simulating the high-speed rotation working state of the to-be-tested turbine blade thermal barrier coating; the service environment simulation equipment is arranged at the other side of the to-be-tested turbine blade thermal barrier coating and used for simulating the service environment of the to-be-tested turbine blade thermal barrier coating in the high-speed rotation working state; the detection equipment is used for detecting damage generated when the to-be-tested turbine blade thermal barrier coating rotates at high speed in the service environment. By means of the experiment test system, the working state and the service environment of the to-be-tested turbine blade thermal barrier coating are simulated, so that key damage parameters of theturbine blade thermal barrier coating in the failure process are conveniently detected in real time, and technical support is provided for process optimization and automatic design of the thermal carrier coating.

Description

technical field [0001] The invention relates to the testing field of thermal barrier coatings of high-pressure turbine blades of aeroengines, in particular to a working condition simulation test system for thermal barrier coatings of turbine blades. Background technique [0002] Aeroengines are an important symbol of a country's core competitiveness. High-pressure turbine blades are the most demanding core components in the engine for bearing and bearing, and are also the short board that restricts the engine. Thermal protection technology is urgently needed. Among the three major thermal protection technologies, the development potential of single crystal and cooling air film technology is very limited. Thermal barrier coatings are recognized as the most feasible way to increase the service temperature of engines. All aviation powers in the world have put the Thermal barrier coating is listed as the core key technology, and my country has also listed thermal barrier coating ...
