 The aim of the work is to create synergistic compositions of corrosion inhibitors and surfactants and to determine the ways of their targeted development for the processes of electric spark machining of steel. During the implementation of the main tasks of the departmental research work, the corrosion and electrochemical behavior of steel in water-salt solutions in the presence of compositions of inhibitors of passivating and adsorption mechanisms of action was investigated and the conditions and causes of synergistic effects in their mixtures were identified; using the Purbe diagram for the Fe - H2O system, the thermodynamic principles of steel passivation and the areas of detection of synergistic effects by inhibitors depending on the metal potential and pH of the medium were determined; the conditions and mechanism of formation of synergistic effects in surfactant mixtures at the interface “solution-air” and “solution-metal” were determined and the possibility of using the method of isomolar series for their development and research was shown; the influence of technological fluids based on synergistic compositions of inhibitors and surfactant mixtures on the characteristics of electric spark machining of steel was investigated. The results of the work are the developed technological fluids MOR-NAU based on synergistic compositions of inhibitors and surfactants.
