Fabrication of superhydrophobic aluminium alloy surface by twice nanosecond laser scanning

The superhydrophobic surface of aluminium alloy was fabricated by nanosecond laser facility. The surface structures of the specimen were observed by scanning electron microscope and confocal laser scanning microscope. Surface hydrophobicity was evaluated by contact angle of deionised water. The phases present in the aluminium alloy surface were identified by X-ray energy spectrum analysis module of scanning electron microscope. The study showed...
