Abstract Superdrophobic surfaces on MB8 magnesium alloy substrate were prepared by regular surface texture by laser manufacturing and perfluorodecyltrichlorosilane (FDTS) self–assembled monolayers deposited on texturing surface. The surface properties and the contact angle of specimen were analysed. The results show that the contact angles of the water droplet on the substrates increase significantly (maximum value 150o) after laser manufacturing and self–assembled monolayers preparation. Rough structure of substrate by laser manufacturing and low surface energy material FDTS self–assembled monolayers are the main factors for preparing superhydrophobic surface. The carrying capacity of platforms maded of superhydrophobic substrate increases with contact angle increasing, and is greater than that of non–superhydrophobic platforms significantly. The calculation results and the existence of “air cushion” are in accord with the Cassie–Baxter model’ state. Comparation of the contact angle between the measurement and theoretical value indicates that hierarchical structure plays an important role in preparation of superhydrophobic surface.
