Some aspects of the theory and practice of corrosion and thermal destruction of metal materialsand of metal coatings

Abstract

On the basis of the statistical approach to the formation of corrosion spots obtained an expression that shows the logarithmic dependence of the corrosion spot area of "defects" of the metal surface or coating. On the basis of a thermodynamic model obtained relationship between corrosion rate, the surface tension of a metal surface and their melting point. A method for determining the thermal stress in the coating on the basis of experimental values of microhardness, measured along and across the sample. On the basis of thermodynamic model derived relationship between the heat resistance of coatings and surface energy. A formula that is suitable for qualitative analysis and forecasting of metal fracture rate and coatings deformation and thermal influences.
