High-pressure turbine blade High-pressure turbine blades as key hot-end components are the decisive limiting factor for the minimum life cycle of modern high-performance engines. They are discarded due to the fretting wear of the blade tips...

A pre-research project of the supporting transmission system of a civil turboshaft engine, to verify the feasibility of laser additive repair method and the typical materials of typical parts of the transmission system. The performance afte...

With the further improvement of engine efficiency, the operating temperature of engine hot-end components has further increased, and the performance requirements of alloys have become higher and higher. Nickel-based superalloys have gradual...

In order to increase the service life of the toothed blade turbine blade, the contact surface is strengthened by surface treatment and surfacing welding is used to increase the wear resistance layer. Compared with conventional surfacing met...

Aircraft engine compressor blades belong to high-temperature, high-pressure, high-speed rotating parts. The working conditions are relatively harsh. The blade tip part is prone to cavitation. If the amount of wear exceeds a certain amount,...
