One-step method using laser for large-scale preparation of bionic superhydrophobic & drag-reducing fish-scale surface

In this study, four bionic fish-scale models were extracted and produced based on the microscopic morphology and the arrangement of scales on the body of Sciaenops ocellatus. A simple, quick and low-cost method using laser was introduced for fabricating the bionic fish-scale surface on aluminum (Al) alloy. Under the action of laser beams, the fish-scale morphology with inclined surface was obtained by controlling the density of laser path and...
