Herein, the research conducted in the field of vacuum‐plasma coating TiVN deposited on the substrate of VT8M‐1 titanium alloy (Ti–5.7Al–3.8 Mo–1.2Zr–1.3Sn) with an ultrafine‐grained (UFG) structure processed by severe plastic deformation (SPD) is explained. The strength characteristics of deposited coating, layer thickness, chemical composition and adhesive properties on substrates with the initial coarse‐grained (CG) and UFG structures are studied. The influence of substrate UFG structure on increasing the hardness of deposited coating and its adhesive characteristics is established. The nature of enhancing the adhesion strength of the coating depending on the substrate microstructure is discussed.
