AB  - Electrochemical characteristics, composition and surface morphology of vinyltriethoxysilane (VTES) coatings on aluminum were investigated. The silane coatings were deposited chemically, by immersion in 2 and 5% VTES, and then cured at 100 degrees C during 10 or 30 min. Surface morphology of VTES films was analyzed by scanning electron microscopy, while the composition was investigated by X-ray photoelectron spectroscopy. The corrosion stability of silane coatings was determined by electrochemical impedance spectroscopy in 0.03% NaCl. The results obtained were compared with the standardized analysis in the salt spray chamber. The percentage of the corroded area was determined by optical microscopy coupled with image analysis. The influence of VTES concentration and curing time on the corrosion stability of silane films on aluminum was shown. The highest corrosion stability was obtained for silane films deposited from 5% VTES solution with 30 min curing, while the lowest stability was determined for silane films deposited from 2% VTES solution with 10 min curing. Surface analysis suggests that the coatings with the highest corrosion stability are related to the intensive siloxane bonding (Si-O-Si), which is favored by deposition from more concentrated VTES solution.

AB  - The corrosion protection of vinyltriethoxysilane (VTES) films on aluminium during exposure to 3% NaCl was investigated using electrochemical impedance spectroscopy (EIS), potential-time measurements and optical microscopy coupled with image analysis. Composition and thickness of films were analyzed using Auger electron spectroscopy (AES) combined with depth profiling. It was shown that films deposited from 5% solution were significantly thicker and exhibited lower porosity and better corrosion stability, as compared to films deposited from 2 vol.% solution. VTES films deposited from 5 vol.% solutions and cured for 30 min exhibited better protection properties than other investigated films.

AB  - The corrosion stability of vinyltriethoxysilane/epoxy coating protective system on aluminium is strongly related to the strength of bonds forming at the metal/organic coating interface. This article is a study of adhesion, composition, electrochemical and transport properties of epoxy coatings electrodeposited on bare aluminium and aluminium pretreated by vinyltriethoxysilane (VTES) during exposure to 3% NaCl. The VTES film was deposited on aluminium surface from 2% vinyltriethoxysilane solution during 30 s. From the values of adhesion strength (pull-off test), time dependence of pore resistance and coating capacitance of epoxy coating (impedance measurements) and diffusion coefficient of water through epoxy coating (gravimetric liquid sorption measurements), the influence of VTES sublayer on the corrosion stability of the electrodeposited epoxy coating was shown. The work discusses the role of the VTES pretreatment in the enhanced adhesion and corrosion stability of epoxy cataphoretic coating. The electrochemical results showed that the aluminium pretreatment by VTES film improved barrier properties of epoxy coating (greater pore resistance and lower coating capacitance). The lower value of diffusion coefficient of water through epoxy coating indicates the lower porosity, while the smaller adhesion reduction points to better adhesion of epoxy coating on aluminium pretreated by VTES film. The composition of the deposited coatings investigated by XPS enabled the clarification of the bonding mechanism.
