Research Progress on Preparation of Metal Superhydrophobic Surfaces by Wire EDM

WEDM is an effective way to prepare metal based superhydrophobic surfaces, which has the advantages of simple process, low cost and environmental friendliness. The surface wettability of materials and principle of WEDM were outlined, and the research progress of preparing superhydrophobic surfaces on aluminum, copper, iron and titanium based metal materials by WEDM was summarized. Moreover, the future development directions were prospected.
