In this study, the architecture of a multilayer metallic material of iron-carbon alloys with an internal protector was developed based on theoretical studies. The operability of the proposed architecture was experimentally verified using gravimetry and electrochemical analysis. The internal position of the protector enabled the modification of the mechanism of corrosion. The stages of corrosion of the multilayer material were revealed; the material was observed as useable until the third layer was perforated. To demonstrate the obtained results, the authors conducted a set of experiments using X-ray microscopy and scanning electron microscopy with an electron probe analysis of the chemical composition. The cost of the developed material is within the same range as widely used corrosion-resistant stainless austenite steels; and in terms of corrosion resistance, this material is comparable to palladium, molybdenum, nickel, and Hastelloy.

Based on the analysis of modern experimental data dedicated to anodic behaviour of silver in solutions containing halide anions, an equation establishing the dependence of the peak-start potential of silver passivation on the potential scan rate, ion halide concentration, and solubility product of silver halide, was obtained. It follows from the proposed equation that the smaller the solubility product value and the potential scan rate are, and the greater the concentration of anion halides is, the anode passivation occurs at a lower potential value. The equation agrees with the experimental data presented in the modern literature rather well. The results can be used in studies aimed at finding the optimal modes of anodic treatment of metals, the development of measures to increase the corrosion resistance of materials, as well as for the quantitative analysis of chlorides, bromides and iodides in solution, including their co-occurrence.
