1. A method comprising:
using a laser-induced continuous explosion shock wave to acquire a nanostructured coating, wherein an intense laser beam with high power density and short pulse is irradiated on a black paint surface of an upper opening of a high pressure resistant glass pipe, a plurality of black paint particles of the black paint surface absorb the laser energy to result in an instantaneous vaporization, a breakdown and an ionization, and then generates a plasma; radiating, by the subsequent laser beam, the plasma, which quickly accumulates energy and initiates an expanding explosion to form an initial plasma explosion shock wave that is to be transmitted in the high pressure resistant glass pipe, wherein the high-temperature and high-energy plasma quickly excites and induces adjacent plurality of black paint particles of the black paint surface to have the same process of instantaneous vaporization, ionization and expansion to a shock wave again; wherein the method is repeated along a black paint strip all the time, whereby a plasma cloud is formed, the explosion shock waves are superimposed layer upon layer, and the shock wave pressure reaching the lower opening jumps; wherein the intense shock wave pressure outputted embeds nanoparticles on a surface of a pre-coated workpiece into the surface of the workpiece to form the nanostructured coating. |
