In view of the common high-pressure turbine I-level blade tip wear failure during the overhaul of a certain type of aero engine, and the poor weldability of the ЖСбУ-ВИ nickel-based casting alloy blades, and the characteristics of easy cracking, WILA has developed a suitable laser cladding Nickel-based alloy powder: The blade tip laser cladding molding process and parameters have been optimized, the mechanical properties of the blade cladding layer at room temperature and high temperature, the heat resistance and oxidation resistance, the cold and hot fatigue performance, and the comparison test of the vibration fatigue of the repaired blade.

The result surface: The working blade repaired by WILA has been verified by the factory and installed and used, and has been in safe service for 2000 hours, which can meet the needs of one engine overhaul cycle.
