Organization Property Researches of the Laser Repair Technology in the Helicopter Engine Turbine Oriented Implement
The repair of the helicopter turbine oriented implement leaf blade was investigated by employing the laser repair technology.The fourth turbine oriented implement leaf blade of a helicopter and the Ni-base alloy were utilized as the substrate and layer cladding material,respectively.The surface figuration,microhardness and microstructure of the cladding layer were studied under laser power of 1-2 kW,scan velocity of 2-15 mm/s,facula diameter of 1-3 mm and thickness of 0.2-0.6 mm.The rigidity analysis,scanning electron microscope (SEM) observations and the macroscopical modality of the repaired leaf blade indicate that laser cladding layers of close organization and good metallurgy union were obtained.Therefore,it is feasible to employ the laser modification technology to repair the turbine oriented implement leaf blade shattered.
