Abstract
The paper presents the results of study of the structure, phase composition and morphology of a nanocrystalline coating produced by reaction synthesis of a three-layer Ti–Ni–Ti nanolaminate. A characteristic feature of the coating is its full crystallinity, gradient structure and the absence of non-metallic inclusions. TEM and XRD analyses showed that reaction synthesis results in formation of a two-layer coating with a thickness of 0.9 – 1.0 μm. The thickness of the outer TiO + TiO2 and inner Ti4Ni2O layers is equal. There are no breaks between the synthesized coating and the substrate. The results of AFM and wetting showed that the surface of the synthesized coating is rougher than that of the deposited Ti–Ni–Ti nanolaminate. It exhibits an island relief and demonstrates hydrophilic properties.
