Abstract
The effects of absorption of elastic energy in a metal-coating-hydrogen system are analyzed; they are caused by permeation of hydrogen through the complex coating and characterize its protective properties. It is shown that hydrogenation of the matrix with gas-thermal coatings results in transformations of β-relaxation components and changes the hydrogen-dislocation effects. The concentration of hydrogen is calculated both for deep-seated and surface layers of the matrix.
