The effect of straining in liquid nitrogen medium on the kinetics of water desorption from copper and iron during heating

The effect of preliminary straining of copper and iron in liquid nitrogen medium, which facilitates intense penetration of nitrogen into surface layers of the metals, on the position of peaks in the temperature dependence of the water molecule desorption rate is considered based on the concepts of dislocation–dynamic diffusion of atoms and molecules of the medium into the surface layers of solids. It is found that preliminary deformation leads to displacements of the peaks towards higher temperatures. Various methods of separation of peaks on the water desorption curve are compared, and the activation energies of desorption in low- and high-temperature regions are estimated. The reasons for the influence of deformation in liquid nitrogen on the characteristics of water molecule desorption upon heating are considered.
