摘要： A method and apparatus for nanocrystallizing a metal surface by laser-induced shock wave-accelerated nanoparticles. The apparatus comprises a control system, a light guiding system, a workbench control system and an auxiliary system, wherein the auxiliary system comprises an air compressor, a paint feeder device, a nanoparticle nozzle, a powder feeder device, an exhaust, a sealed working chamber and a metal nanoparticle recycler device. The method comprises the following steps: pre-processing and fixing a workpiece; activating the air compressor to feed a powder; controlling and adjusting the paint feeder device to eject a black paint; transmitting a high-power pulse laser beam; recycling excess metal nanoparticles; and rinsing non-vaporized/ionized black paint off a surface of the workpiece.

摘要： A method and apparatus for acquiring a nanostructured coating on a metal surface by using an intense shock wave generated by continuous explosion of a laser-induced plasma is provided. The method comprises: irradiating a laser beam on a black paint surface of an upper opening of a high pressure resistant glass pipe having a black paint strip arranged therein; the black paint absorbing the light energy and producing a plasma; generating an initial plasma explosion shock wave; transmitting the initial plasma explosion shock wave in the high pressure resistant glass pipe; generating a plasma cloud reaching a lower opening of a glass catheter; and, the shock wave pressure outputted embedding nanoparticles into a surface of a workpiece. The apparatus comprises the high pressure-resistant glass pipe with a zigzagging switchback shape or a spiral and inverted cone shape.
