Preparation of superamphiphobic aluminium alloy surface based on laser‐EDM method

In order to achieve superamphiphobic surface of aluminium alloy, a method based on laser-EDM (electrical discharge machining) was proposed. By means of laser etching, the size of the controllable micrometre square column structure could be prepared on the surface of aluminium alloy. Then combined with the electric processing method, the binary micro-nano rough structure was constructed and modified with fluorosilane methanol solution, and the...
