Using two different types of protective coatings, we examined the protection of magnesium alloy (AZ61) with composition of Mg(93)–Al(6) –Zn(1) against corrosion in neutral 3.5% NaCl solution. We treated the alloy with a novel silane polymer coating that demonstrated viable in protecting the surface against corrosion. The hybrid protecting film is composed of 1,2 bis(triethoxysilyl)ethane-poly(vinyl alcohol). Also we examined an alternative approach to coat the magnesium-based alloy with a layer containing nickel and TiO2 nanoparticles and followed by applying a protective silane film. The silane film was synthesized from a silane precursor (1,2-bis(triethoxysilyl)ethane) using a sol–gel cross-linking method. The surface of the bare and coated Mg alloy was evaluated before and after exposure to the corrosive medium using structural, surface and electrochemical techniques. Structural techniques include X-ray photoelectron spectroscopy. Scanning electron microscopy/energy-dispersive X-ray spectroscopy analysis was used to explore the surface morphologies and structures. The electrochemical techniques used were potentiodynamic polarization and electrochemical impedance spectroscopy. The Mg alloy coated with the hybrid films has been tested for prolonged exposure to the chloride solution, and both coatings have proved effective in protecting the Mg alloy. [ABSTRACT FROM AUTHOR]
