To enhance durability and adhesion of superhydrophobic surface,an integrated superhydrophobic calcium myristate(Ca[CH3(CH2)12COO]2)coating with excellent corrosion resistance was fabricated on AZ31 magnesium(Mg)alloy via one-step electrodeposition process.Field-emission scanning electron microscopy,Fourier transform infrared spectrometry and X-ray photoelectron spectroscopy as well as X-ray diffraction were employed to investigate the surface characteristics(morphology,composition and structure)of the coatings.Hydrophobicity of the coating was evaluated by means of con-tact and sliding angles.Additionally,potentiodynamic polarization,electrochemical impedance spectroscopy and hydro-gen evolution tests were conducted to characterize the corrosion resistance.Results indicated that the coating exhibited super-hydrophobicity with large static water contact angle(CA)and small sliding angle of 155.2°±1.5° and 6.0°±0.5°,respectively,owing to spherical rough structure and low surface energy(7.01 mJ m-2).The average hydrogen evolution rate(HERa)and corrosion current density(icorr)of the coated sample were 5.3 μL cm-2 h-1 and 5.60×10-9 A cm-2,about one and four orders of magnitude lower than that of AZ31 substrate,respectively,implying the excellent corrosion resistance.The CA of the coating remained 155.6°±0.9° after soaking for 13 days,showing the super-hydrophobicity and stability of the coating.Simultaneously,the large critical load(5004 mN)for the coating designated the outstanding adhesion to the substrate by nano-scratch test.
