In this paper, single and multilayer superhydrophobic composite coatings, based on fluorocarbon resin and micro-tourmaline and nano-TiO2 powers, were prepared by conventional air spray method. The tourmaline and TiO2 particles were modified by fluoroalkylsilane. The wettability and marine corrosion of the coatings surfaces were investigated respectively by contact angle measurement and Electrochemical Impedance Spectroscopy (EIS) method, and their morphology was examined by Scanning Electron Microscopy (SEM). The results showed that the water contact angle of coatings was mainly controlled by the mass ratio of the fluorocarbon resin and particles. The contact angle increased with the increase of particle concentration, which reached about 156° when the mass ratio of the particles and fluorocarbon resin was 2:1 for single and multilayer composite coatings, but the impedance valve of the multilayer is higher than that of the single layer.
