“…4a) results of a weak peak at 3698 cm −1 . The volume fraction of Ca[CH 3 (CH 2 ) 12 COO] 2 for immersed coating was 26.05%, a little lower than 28.95% of the coating before soaking, inferring that there was a slight dissolution or the decrease of the coating density during the dipping process, which resulted in more X-ray penetration and increased Mg fraction of 73.37% (71.05% before immersion).…”

To enhance durability and adhesion of superhydrophobic surface, an integrated superhydrophobic calcium myristate (Ca[CH 3 (CH 2 ) 12 COO] 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 contact and sliding angles. Additionally, potentiodynamic polarization, electrochemical impedance spectroscopy and hydrogen 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 (HER a ) and corrosion current density (i corr ) 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.

“…Therefore, to solve these problems, copolymerization of the main monomer with other monomers, stepwise coating or doping with organic and inorganic components (composite coating) have been reported as some of the methods being used. The introduction of composites into the matrix of polymer, alloying is the most optimal way to obtaining polymer coatings with a clear structure, high conductivity and high anti-corrosion properties [16][17][18].…”

Polyanisidine (POA) and polyanisidine-molybdate (POA−MoO42-) coatings have been successfully synthesized on steel grade СТ3 from aqueous solutions of oxalic acid by electrochemical method using cyclic voltammetry. The morphology and composition of these films were characterized by scanning electron microscopy (SEM) and energydispersive X-ray (EDAX) methods. It was proven that the introduction of MoO42- into the polyanisidine matrix raised the corrosion resistance of the POA coating and also improved its adhesion properties. The protective properties of steel grade CT3 with POA and POA-MoO42- films were studied using potentiodynamic polarization in 3.5% NaCl solution. The results showed that ions improve anti-corrosion properties of POA films.
