N2  - The gradient coating synthesized on a nickelide titanium sample by sputtering a three-layer Ti-Ni-Ti laminate
and annealing in air at 950–1000 °С was studied by XRD, SEM, TEM, and AFM methods. The thickness of the
 sputtered laminate layers was chosen equal to 0.5–1.0 μm to study the composition, structure and sequence of
 formation of the crystalline phases of the gradient coating. This thickness was sufficient for SEM and TEM studies
 and admissible large for XRD studies of phase composition. SEM and TEM techniques were used to determine the
 depth and patterns of grains occurrence of titanium carbonitrides. TEM and XRD techniques revealed that reactive
 synthesis of the coating is followed by transformation of the external amorphous layer of deposited titanium
 into heterogeneous crystalline titanium oxides. Crystallization of the oxide phase causes an increase in
 the volume of the external layer and intergranular cracking of the surface. AFM method showed an island
 microrelief of the external titanium layer formed during synthesis. The reaction synthesis of a multilayer laminate
 allows obtaining multifunctional nano-structured multilayer coatings with high chemical, mechanical
 and tribological characteristics, which ensures bioinertness of the surface of titanium nickelide implants
