Metal Surface Engineering Based on Formation of Nanoscaled Phase Protective Layers
The processes of formation of phase protective layers in the presence of numerous individual inhibitors and their mixtures have been investigated. The results of characterization of the protective films for determining the influence of the concentration ratio of the mixture components and the deposition conditions on the distribution of elemental composition within layer thickness using Auger spectroscopy with ion etching have been presented. The influence of the metal potential and pH on the mechanism of action and the efficiency of the individual additives and their compositions has been determined. It was shown that the most dense nanoscale phase layers that ensure highest protective efficiency may be formed using synergistic mixtures of inhibitors with different mechanisms of action.
