“…In recent decades, extensive studies of atmospheric corrosion have been carried out and yielded results of academic and practical importance. For example, corrosion tests of standard metals were conducted under international programs, including continental and coastal test sites: ISO CORRAG [1], MICAT [2,3], UNECE [4], the OSD project [5] and under programs of individual countries [6][7][8][9][10][11][12]. The results of these tests enabled the estimation of the corrosion resistance of metals in various regions of the world.…”

Four 1-year tests of metal samples (carbon steel, zinc, copper, aluminum, and D16 alloy) were carried out at locations with coastal and rural atmospheres to determine corrosion losses and the rate of chloride deposition ([Cl-]) on the upper and lower sample sides. [Cl-] were determined for different orientations relative to the sea winds on coastal sites. A methodology for testing metal samples is presented and the values of the first-year corrosion losses of metals (C1) are reported. It is shown that the corrosion of metals is significantly affected by the season of when the samples are installed. The atmosphere corrosivity under each conditions of sample exposure is estimated by the C1 values calculated using the developed dose-response functions (DRFs). It has been shown that the DRFs can be used to predict C1 and estimate the atmosphere corrosivity categories at locations with various types of atmosphere and under various exposure conditions.

The results of applying intermediate products and petrochemical wastes for making corrosion inhibitors are analyzed herein. Behavior of a number of 1,3-diheterocycloalcanes-based corrosion inhibitors is reviewed. Analysis of corrosion-electrochemical test results with steel samples to be applied in oil and gas facilities construction has become the principal approach to this study. Kinetic parameters of cathodic reactions are found by analyzing Tafel sections of polarization curves taken in the blank medium while injecting various compounds thereto. Experimental criteria defining the mechanism of cathodic release of hydrogen both in uninhibited and inhibited acidic corrosive media are found. 1,3-dioxolane derivatives are not demonstrated to actually affect the cathodic reaction parameters but they are blocking inhibitors; while oxazines and carbamates are mixed inhibitors. The results of corrosion-electrochemical tests may be used to study the mechanism of the corrosion inhibition with the studied compounds.

Theoretical concepts of inhibition mechanism in metal corrosion and forecasting of protective properties of substances are connected with experimental research of surface-active materials adsorption on metal surface. Application of petrochemicals, including intermediate products and petrochemical wastes for making new highly efficient and quite cheap corrosion inhibitors is promising. Research results of adsorption of some 1,3-diheterocycloalcanes-based compounds by method for measuring double-electric layer capacity appearing in “metal-electrolyte” interface in blank corrosion medium are reviewed herein. Therewith both blocking and energy effects of inhibitors are found to be the most efficient at first approach. Blocking effect is reducing area of metal surface affected by corrosion. Energy or ψ 1-effect occurs due to changing of double-electric layer structure in “metal-corrosion medium” interface. Adsorption results may be used to study corrosion inhibition mechanism by the analyzed compounds.
