Owing to the severe service conditions, components made from nickel-based superalloys are susceptible to cracking and wear. Laser repair technology can restore the mechanical properties of damaged structural components, thereby prolonging their service life. To enhance the quality of repaired components, ultrasonic vibration has been integrated into the laser repair process to suppress defects and improve performance. The work aims to investigate the impact of ultrasonic vibration on the microstructure and mechanical properties of the trapezoidal groove repair zone in nickel-based superalloy components repaired by laser technology.
