Abstract

A turbine blade thermal barrier coating operating condition simulation test system, including working state simulation equipment, service environment simulation equipment and testing equipment; The blade thermal barrier coating connection is used to simulate the high-speed rotating working state of the thermal barrier coating of the turbine blade to be tested; the service environment simulation equipment is set on the other side of the thermal barrier coating of the turbine blade to be tested to simulate the thermal The service environment of the barrier coating under high-speed rotating working conditions; the detection equipment is used to detect the damage generated when the thermal barrier coating of the turbine blade to be tested rotates at high speed in the service environment. Through the experimental test system provided by the invention, the working state simulation and service environment simulation of the thermal barrier coating of the turbine blade to be tested are carried out, so as to detect the key damage parameters in the failure process of the thermal barrier coating of the turbine blade in real time, and to realize the thermal barrier coating Process optimization and independent design provide technical support.

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 ...
