“…10(b) indicates clearly that the passive film contains an inner chromium-rich layer and an outer iron-rich layer. The bi-layer structure of passive film has been found for stainless steel in acidic, alkaline and chloride-contained solutions by many authors [42][43][44][45]. The amount of oxidized nickel and molybdenum are very limited in the film in comparison to the bulk concentration, and primary of them exist in the outer layer.…”

“…At these two temperatures the slopes of the straight lines in Region I increase with formation potential. It has been reported in the literature that the concentration of Cr(III) in the passive films formed on stainless steels, Ni‐Cr alloys and pure Cr increases with increasing formation potential within the passive region. The increase of Cr(III) within the passive film implies a decrease in the number of cation vacancies, V Cr 3' , and consequently higher negative slopes in the p ‐type semiconductivity zone below the E FB (Region I) according to eq.…”

The passive behaviour of Alloy 31, a highly‐alloyed austenitic stainless steel (UNS N08031), has been investigated in a LiBr heavy brine (700 g/l) at different temperatures using potentiostatic polarisation and Mott‐Schottky analysis. Cation vacancies have been found to be the dominant defect in the passive films formed on Alloy 31. An increase in temperature enhanced the generation of cation vacancies at the film/solution interface and raised the steady‐state passive current density. The density of defects within the passive film also increased significantly with temperature, making the film more conductive and less protective against localised attacks.

E-mail: kiruhancev-korneev@yandex.ru.Проанализировано современное состояние исследований функциональных поверхностей и покрытий с помощью метода оптической эмис-сионной спектроскопии тлеющего разряда (GDOES). Описаны его основные принципы. С целью определения требований к образцам и вы-явления потенциальных возможностей метода проведены GDOES-исследования покрытий с различными составами и структурными харак-теристиками, полученных с использованием нескольких способов. Ключевые слова: оптическая эмиссионная спектроскопия тлеющего разряда, GDOES, функциональные поверхности, покрытия, пленки, хи-мический анализ, элементный профиль.The current state of functional surface and coating studies by glow discharge optical emission spectrometry (GDOES) has been analyzed. The main principles are described. For the purpose of determination of the requirements to samples and detection of potential possibilities of the technique, the GDOES-investigations of different composition coatings and structural characteristics, which are obtained by some procedures, have been carried out.
