Conclusions

An attempt has been made to apply the method of mathematical experiment planning in a study of the metal-solution system, with subsequent computer treatment of numerical information.

A stimulating effect of H2S along with the H2SO4 has been demonstrated in a model solution of the plasticizing bath. For the first time, the action of PEG-35 as a component which activates the anodic process of solution of 06KhN28MDT alloy, and an opposite action of Berolvisco 314 has been defined. Their roles differ in establishing the potential of the alloy; PEG-35 displaces ϕ in the positive direction; Berol-visco 314 displaces it in the negative direction.

The contributions of the components of the medium and of temperature to the total value of the anodic current density at the potential for the onset of passivation of 06KhN28MDT alloy and of its corrosion potential have been differentiated.

The application of various plans and of a computer has made it possible to obtain equations which adequately reflect connections in the metal-solution system with a minimum expenditure of effort and time.
