“…Эллипсометрический метод применяется также и для исследования адсорбции летучих ингибиторов коррозии (ЛИК). Так, в [34] авторы исследовали взаимодействие нитрита дициклогексиламмония и дициклогексиламин на подложках из чистого железа и платины методом эллипсометрии.…”

В статье продолжен анализ применения метода эллипсометрии для исследования ингибиторов коррозии металлов и рассмотрена совместная, а также индуцированная адсорбция ингибиторов и созданные на их основе композиции. Приведены примеры определения размеров адсорбированных монослоев, кинетики их роста. Помимо уже ставших обычным применением эллипсометрии для исследования адсорбции ингибиторов из водной фазы, рассматривается применение этого метода для летучих ингибиторов коррозии и камерных ингибиторов коррозии.

“…Ellipsometry may be characterized as reflection polarimetry or polarimetric spectroscopy, and it involves the measured effect of reflection on the state of polarization of light. 97 Such measurements may be interpreted to yield optical constants of the reflecting material or when the reflecting material is a filmcovered substrate, the thickness and optical constants of the film.…”

“…Earlier reports on the application of ellipsometry were made in 1987. 97 Interactions of dicyclohexylamine and dicyclohexyl ammonium nitrite on iron and platinum were made. The thickness of a film with a given refractive index and absorption coefficient can be characterized with the aid of polar diagrams showing the dependence of the phase shift (∆) and the tan () on the thickness of the film.…”

When present as vapors, certain organic compounds offer inhibition against the corrosion of ferrous and nonferrous materials. The inhibitors include aliphatic, aromatic, cyclohexylamines, aminonitrobenzoates, heteroalkylated lower amines, etc. The mechanism of inhibition offered by these compounds was discussed and an unified mechanism was presented. Various methods of evaluating inhibition efficiency were discussed with a special reference to surface film characterization techniques. Methods of application of the vapor phase inhibitors and their industrial uses also were presented.

The difference in electroluminescence intensity for the peak obtained with the reduction of Fe(CN)i-and the hypohalites at n-GaAs cannot, however, be explained on the basis of Fig. 9. Although a change is observed in the mechanism of the second charge transfer step (from hole injection (3a) at low light intensity to electron capture (3b) at high light intensity) such a change is only expected after the masstransport limited current has been reached. That only very weak electroluminescence is observed in the onset of the hypohalite reduction at n-GaAs must therefore mean that the value of the rate constant for hole injection in the second step (kp2) is lower than for p-type GaAs. This might be due to an effect of the electric field on the hole injection rate. Adsorption f Corrosion Inhibitors / Corrosion / Electrochemistry / Inhibition / SurfactantsNonylphenolepolyethyleneglycoles (NPG) are characterized by means of electrochemical methods. We made electrochemical impedance spectroscopy and current density-potential measurements at superpure iron electrodes in K N 0 3 solution with and without addition of NPG. In order to acquire some knowledge about the electrical potential-distance profile at the electrode surface of iron, we made Zeta potential measurements at dispersed a-Fe203 particles. Adsorption phenomena of NPG at electrode surfaces free of any oxide layer were studied by a.c. polarography (tensammetry) at the dropping mercury electrode. It is shown that NPG can inhibit the corrosion reaction of superpure iron in neutral solutions as combined anodic/cathodic inhibitors, but increase the cathodic process in weak acid solutions.
