“…It is a surface phenomenon and, due to the great variety of metallic materials used and their different properties of resistance to corrosion, a series of protection processes for metallic surfaces were and have been developed. Amongst the most employed surface treatment processes, is phosphating [15,19]. Phosphating is a conversion treatment which enables the surface coating with a phosphate insoluble salt layer, most of the times zinc phosphate [20,21], aiming at protection against corrosion, preparation for painting, electrical separation, and decoration [20,21].…”

A new coating made of niobium pentoxide, obtained through the sol-gel process, was developed for the carbon steel (SAE 1010). The corrosion protection provided by this coating was evaluated through electrochemical tests such as: open circuit potential, electrochemical impedance spectroscopy and anodic potentiodynamic polarization in NaCl 0,5 mol L -1 solution. The morphology and composition of the coatings were analyzed using scanning electronic microscopy, energy dispersive spectroscopy and X-ray diffractions. A zinc phosphate coating was used as standard test for comparison of results. The electrochemical measurements revealed that: (1) The Nb 2 O 5 coating dislocates the corrosion potential towards more positive values; (2) higher impedance values were found for the Nb 2 O 5 coated samples; and (3) lower current density values were found for these samples. The electronic micrograph revealed that there was alteration in the morphology of the carbon steel surface due to the Nb 2 O 5 deposition. The EDS spectra confirmed the niobium coating deposition, as a peak regarding this element was obtained in the spectra. The X-ray diffractograms confirmed the presence of the phases in the Nb 2 O 5 coating. This new coating increases protection of the carbon steel against corrosion and presents an alternative to replace phosphating.

“…Their main purpose is to accelerate the treatment rate, and also to alter the structure and improve protective properties of phosphate coats. The additives vary in mechanism, nature, properties and effectiveness [1,7]. The most important group of additives are chemical accelerators.…”

“…The most important group of additives are chemical accelerators. The group encompasses inorganic oxidizers (nitrites, nitrates, permanganates, persulfates, chlorates, fluorides: [1,7,19], and also metals that are nobler than iron (Cu, Ni, etc.) and their compounds [20,21].…”

“…to phosphate baths has also been described and papers proposing them are still being published. Particularly, studies on the influence of triazole compounds [7] and ethanolamine [22] additives to phosphate baths on the corrosion resistance of the metal substrate have been carried out. According to [23,24], the use of pure silica in combination with cationic surfactants based on triethylamine and long-chain alkyl halides led to the formation of the highly-porous small-grain coat with good adhesion.…”

“…This property can be efficiently used to produce coatings with desirable properties. A conversion coating is the most effective method to prevent corrosion of steel in a wide range of applications [7][8][9]. Recently, we investigated the effect of Tween 80 surfactant on the corrosion resistance of Zn-phosphated steel using potentiodynamic polarization, electrochemical impedance spectroscopy, SEM and EDX analysis techniques [10].…”

The conducting polymers, poly-o-chloroaniline and poly-o-aminobenzoic acid have been synthesized from their monomers on steel surface by cyclic voltammetry method in aqueous oxalic acid solution containing different concentrations of Tween 80 surfactant. The polymers were characterized by scanning electron microscope SEM. Potentiodynamic polarization and electrochemical impedance spectroscopy EIS techniques have been used to investigate the corrosion behavior of the polymer coated steel electrodes in 0.5 M H 2 SO 4 solution. Effect of the surfactant on the electropolymerization process and the protection efficiency of the polymerized coat have been studied. Effect of substituent in the molecule of the monomer on the protection efficiency of the polymerized coat has been also studied.
