| Samenvatting: | Заглавие с экрана Coatings deposited by multipass electron beam surfacing of powders that contain nitrogen in equilibrium concentration was investigated. Distribution of crystal lattice microstrains in the coating, which form stresses of the 1-st and 2-nd kinds, was experimentally obtained. Owing to the thermal and structural gradients in multilayered coating, the complex stress is formed, which is characterized by sign change of crystal lattice deformation through the coating thickness andincreased dislocation density. Due to the action of residual stresses in the coating, the relaxation processes are developed by means of mechanical multiple twinning. |
