The metallic glass ribbons (MGRs) industrially produced by the single roller melt-spun method have
many surface defects such as pits and scratches. In this study, it was attempted to repair the surface
defects of Zr-based MGRs via nanosecond pulsed laser irradiation. The experimental results showed that
the roughness of laser-repaired surfaces was significantly reduced compared to the melt-spun surface,
and the surface topographies and morphologies were sensitive to the laser parameters. With optimal
laser parameters, the smooth and defect-free surface could be achieved. This work offers a convenient
and high-efficiency approach for repairing the surface defects of MGRs.
