Abstract
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.
