Deposition of nanostructured multi-layered coatings on the basis of Zr-Y-0 was implemented by the pulse magnetron methods. Structural-phase states and morphology of the nanostructured coatings were investigated by SEM and the high-temperature TEM method. The high-temperature TEM revealed the presence of reversible phase transition of the tetragonal phase to the monoclinic phase, which can ensure stress relaxation and closure of surface cracks
