报告内容:

Laser and nanotechnology has brought revolutions in advanced manufacturing. At the first part, we will present the laser technology for nanosintering, nanobrazing, photonic reduction, carbonization, 2D-3D printing with specially highlighting nanomaterials for macro, micro and nanoscopic device fabrication by integrating high power diode laser, nanosecond fiber laser and femtosecond lasers. We will illustrate the latest progress on laser brazing for turbine and vane repairing, laser 3D direct writing of flexible sensors and 3D printing of thin film Al-air batteries. We then discuss the future developing trend and introduce laser-based super-resolution manufacturing. At the second part, we will review our research on the development of Ag-, Cu-, Ni-nanopastes, high entropy alloys and reactive multilayer films as brazing materials without using a melting point depressant. The application is further developed for Ni-based alloys brazing, blades and vanes repairing, dissimilar metallic joining and Ti-alloy sealing.
