Investigation of micron-sized fish-scale surface structures on tool steel surfaces using laser galvanometer scanning

Micronized structured surface exhibits excellent surface functions for surface science applications. However, the cost is high for fabricating, especially specialized structure surfaces. The work prepared the micron-sized fish-scale surface structures on rough DC 53 tool steel surfaces. CW (continuous wave) laser beam irradiation method was used from a scanning galvanometer in the filling scan mode. The surface morphology and structure before...
