METHOD AND APPARATUS FOR ACQUIRING NANOSTRUCTURED COATING BY EFFECT OF LASER-INDUCED CONTINUOUS EXPLOSION SHOCK WAVE

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. The method comprises: irradiating a laser beam on a black paint surface of an upper opening of a high pressure-resistant glass pipe (21) 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 (4); transmitting same in the high pressure-resistant glass pipe; generating a plasma cloud reaching a lower opening of a glass catheter; and a shock wave pressure outputted embedding nanoparticles (22) into a surface of a workpiece (25). The apparatus comprises the high pressure-resistant glass pipe (21) having a zigzagging switchback shape or a spiral, inverted cone shape.
